The Steel Union

Conventional armed forces

The balanced faction. A complete roster from infantry through tanks and mechs to air power, with no special mechanic — what you see here works exactly as expected.

  • A solid answer for every role
  • No build-up special rule, quick to learn
  • No mechanic that can backfire
  • No pronounced strength to decide a match with
  • Wins through execution, not through quirks

Almost all of it sits behind research: every production building offers one combat unit to begin with, everything else you unlock in the tree.

Arachnos

Cost
500 Fe · 300 Cu · 385 Ti
Structure
900
Damage
78 at 180
Speed
12
Armor
Tier 25

The Arachnos is a massive 8-legged combat mech with three independent weapon systems on a fully rotating platform - twin cannon, rocket launcher and anti-infantry MG fire simultaneously in any direction, independent of the walking direction.

Artillery

Cost
100 Fe · 55 Cu · 20 Ti
Structure
74
Damage
57.8 at 240
Speed
16.5
Armor
Tier 9

The artillery bombards targets at enormous range with area damage - ideal against buildings and defense towers, but inaccurate against moving targets and barely armored itself.

Siege Train

Cost
420 Fe · 225 Cu · 255 Ti
Structure
620
Damage
20 at 130
Deployed
150 at 500 (from 160)
Speed
11
Armor
Tier 23

The Siege Train is the heaviest demolition weapon the Steel Union field: rolled up and unfolded it throws 500 paces - beyond the reach of ANY tower. The price is being rooted: six seconds to deploy, five to pack up, and helpless in between. Left without escort, it falls to the first squad that gets through.

Breaker

Cost
210 Fe · 105 Cu · 55 Ti
Structure
180
Damage
14 at 120
Deployed
95 at 355 (from 110)
Speed
15
Armor
Tier 16

The Breaker is a siege mortar: mobile it carries only a light backup gun, deployed it lobs shells 355 paces - farther than any standard tower. Against walls, gates and buildings its calibre ignores armour; against vehicles it achieves next to nothing. Deploying takes three seconds, and it is defenceless throughout.

Drone Pilot

Cost
45 Fe · 20 Cu · 10 Ti
Structure
50
Speed
12
Armor
Tier 2

The drone pilot sends a kamikaze drone over a long distance - deadly against infantry, poor against vehicles - but then has to walk back to the barracks unarmed to reload.

Flak Tank

hits air
Cost
110 Fe · 50 Cu
Structure
240
Damage
30 at 240
Speed
16.5
Armor
Tier 9

The flak tank fights airborne targets ONLY - defenseless against anything on the ground, so it needs its own protection. In return it keeps the sky over the base clear with a high rate of fire and long range.

Flamethrower

Cost
35 Fe · 10 Cu
Structure
70
Damage
14 at 62
Speed
13.5
Armor
Tier 3

The flamethrower burns whole infantry groups at once at close range - against armor it does almost nothing. It seeks out infantry even when a vehicle is closer. When it dies, its fuel tank goes up and takes surrounding infantry with it - including your own.

Ghost

Cost
120 Fe · 55 Cu · 35 Ti
Structure
60
Damage
50 at 200
Speed
15
Armor
Tier 2

The Ghost is a cloaked elite sniper: kills infantry with one shot and stays invisible until it fires or the enemy gets too close. Besides the barracks it also needs an experimental works; only half damage against vehicles/mechs.

Grenadier

Cost
30 Fe · 10 Cu
Structure
40
Damage
24 at 110
Speed
13.5
Armor
Tier 2

The grenadier throws grenades with area damage - strong against dense infantry and vehicle formations, weak against single targets.

Harvester

Cost
60 Fe
Structure
80
Speed
27
Armor
Tier 9

The harvester mines ore and delivers it to the refinery - the closer the refinery is to the ore, the shorter the trips and the more harvesters can work efficiently.

Assault Mech

Cost
60 Fe · 35 Cu · 30 Ti
Structure
140
Damage
60 at 175
Speed
22.5
Armor
Tier 18

The Titan mech is the mech factory's counterpart to the heavy tank: a bit more expensive, with longer range, but more vulnerable to critical hits.

Heavy Tank

Cost
120 Fe · 60 Cu · 35 Ti
Structure
235
Damage
58 at 160
Speed
19.5
Armor
Tier 20

The heavy tank is the heaviest unit of the regular tank line - hardly any target withstands its shot for long, but it itself takes the longest to get anywhere.

Blast Furnace

Cost
520 Fe · 290 Cu · 340 Ti
Structure
2060
Damage
78 at 285
Speed
8
Armor
Tier 25

The Blast Furnace is a smelter on tracks: it devours wrecks around it and casts fresh tanks on the spot - a rolling factory at the front. The more that lies on the battlefield, the more reinforcements it turns out. Most of the scrap's value is lost in the process; it is no replacement for a refinery.

Humvee

Cost
30 Fe · 10 Cu
Structure
65
Damage
11.5 at 82
Speed
33
Armor
Tier 9

The Humvee is cheap, fast and deadly against infantry - against vehicles and mechs, however, it does little damage.

Impulse

Cost
300 Fe · 170 Cu · 215 Ti
Structure
180
Speed
21
Armor
Tier 7

The Impulse fires an EMP burst that completely disables enemy vehicles, mechs and defense towers in the area for several seconds - it deals no damage itself.

Attack Helicopter

flying
Cost
80 Fe · 45 Cu · 10 Ti
Structure
90
Damage
18 at 150
Speed
54
Armor
Tier 6

Unlike the jet, the attack helicopter can hover in place and fire - slower and tougher than the jet, but without an attack run. It shares the free landing pads with the other hoverers to reload.

Fighter Jet

flying
Cost
90 Fe · 55 Cu · 20 Ti
Structure
55
Damage
70 at 150
Speed
140
Armor
Tier 5

The fighter jet is the fastest unit in the game: it takes off from the airfield, flies over its target in an attack run and returns to reload - its airfield is also its permanent home base. Its rockets also hit airborne targets. Untouchable on the ground, but flak and guided-missile squads reliably bring it down.

Combat Engineer

Cost
60 Fe · 20 Cu
Structure
40
Speed
13
Armor
Tier 2

The Combat Engineer is an unarmed engineer: send it (right-click) onto an enemy building to capture it - if the building is above 50% health it first sabotages it (dealing 51% damage) and a SECOND engineer then captures it; if it is already below 50%, it captures immediately. Growth buildings are organic and cannot be captured. Sent onto a damaged building of your own, it fully repairs it. In every case it is consumed - and it is fragile, so protect it on the way.

Colossus

Cost
200 Fe · 85 Cu · 85 Ti
Structure
300
Speed
18
Armor
Tier 9

The Colossus is a giant harvester with triple cargo space and double mining speed - slower, but a rolling ore depot.

Light Tank

Cost
70 Fe
Structure
95
Damage
24 at 110
Speed
29.25
Armor
Tier 12

The light tank is the entry point into the tank line: faster and cheaper than its heavier upgrades, but with less firepower and armor.

Sky Scout

flying
Cost
45 Fe · 20 Cu
Structure
30
Speed
42
Armor
Tier 5

The Sky Scout is a fast, unarmed reconnaissance drone from the helipad: twice the Humvee's sight range reveals the map early and scouts enemy bases and troop movements. Extremely fragile - any flak hit brings it down.

Mammoth Tank

Cost
400 Fe · 215 Cu · 255 Ti
Structure
900
Damage
70 at 170
Speed
10.5
Armor
Tier 23

The Mammoth tank is the heaviest unit in the game: twin cannon plus an independent rear rocket launcher. Unique self-repair that, alone among all units, keeps running even in combat (up to 25% HP) - but the full 50% only out of combat and only from level 5.

MCV

Cost
500 Fe · 255 Cu · 130 Ti
Structure
120
Speed
13.5
Armor
Tier 7

The MCV drives to any point on the map and can be deployed there into another command center - the only way to expand the base to a new location or rebuild after a loss.

Medium Tank

Cost
90 Fe · 35 Cu
Structure
142
Damage
30 at 139
Speed
24
Armor
Tier 16

The medium tank is the all-rounder of the tank line: no specialist, but weak in no category - a solid choice when you don't want to decide between speed and firepower.

MLRS

Cost
130 Fe · 70 Cu · 45 Ti
Structure
65
Damage
16 at 260
Speed
18
Armor
Tier 9

The MLRS fires a salvo of rockets that blanket an entire area - devastating against bases and dense formations, but very vulnerable and imprecise against single targets. The only siege unit with friendly fire: the salvo also hits your own troops in the spread radius, so keep your distance from your own army.

Phantom

Cost
250 Fe · 130 Cu · 170 Ti
Structure
160
Damage
40 at 170
Speed
25.5
Armor
Tier 9

The Phantom is a cloaked rocket tank: invisible to the enemy until it gets close or the Phantom fires.

Missile Squad

hits air
Cost
35 Fe · 15 Cu
Structure
50
Damage
60 at 170
Speed
12
Armor
Tier 3

The guided-missile squad is the infantry's answer to everything armored and everything airborne: its guided rockets punch through heavy armor reliably (but don't hit guaranteed) and, as the only Steel Union infantry, also bring AIRCRAFT down from the sky - reaching 50% farther against them than on the ground. Against infantry it is clearly inferior.

Rocket Mech

Cost
130 Fe · 70 Cu · 55 Ti
Structure
95
Damage
8.4 at 245
Speed
18
Armor
Tier 13

The rocket-launcher mech fires a long salvo of precise rockets from its shoulder pods - clearly more accurate than the MLRS against individual vehicles and infantry, but with less total damage against bases and defenseless at close range. As with the MLRS, the salvo also hits your own troops in the spread radius.

Field Repair Truck

Cost
70 Fe · 30 Cu
Structure
100
Speed
30
Armor
Tier 9

The Field Repair Truck is a rolling workshop: within its aura friendly vehicles and mechs repair much faster - so a battered armoured line does not have to pull back to the workshop first. It cannot treat infantry; that is what medics are for. Unarmed itself, it belongs behind the front.

Rifleman

Cost
15 Fe
Structure
50
Damage
10 at 80
Speed
15
Armor
Tier 2

The rifleman is the cheapest combat unit in the game and gets noticeably better with every battle - a freshly trained rifleman hits far less often than an experienced one.

Scout Mech

Cost
40 Fe · 20 Cu
Structure
63
Damage
21 at 80
Speed
31.5
Armor
Tier 10

The scout mech is built for reconnaissance: high speed and wide sight, but only limited firepower in direct combat.

APC

Cost
70 Fe · 30 Cu
Structure
140
Speed
28.5
Armor
Tier 9

The APC carries up to 5 infantry quickly across the map, e.g. to bring reinforcements to the front or slip infantry behind enemy lines - unarmed but solidly armored. When destroyed, the passengers disembark alive.

Barracks

Cost
140 Fe
Structure
220
Armor
Tier 13
Power
-30

The barracks trains infantry and also serves as a field hospital - infantry near it is healed automatically.

Build Hub

Cost
50 Fe
Structure
120
Armor
Tier 13
Power
-10

The build hub extends the area in which new buildings may be erected - a cheap way to expand the base toward ore deposits or the front line without needing a second command center.

Bunker

Cost
110 Fe · 30 Cu
Structure
900
Armor
Tier 15

The Bunker is unarmed itself, but can be garrisoned with up to 5 infantry (right-click, like a transport): each occupant fires its OWN weapon out of the embrasures - +40% range, but slightly reduced damage. Pick the garrison to match the enemy (riflemen vs infantry, anti-tank vs vehicles). The occupants are untargetable while the bunker stands - if it falls, they die with it. Requires a barracks.

Command Center

Structure
900
Armor
Tier 13
Power
50

The command center is the heart of the base: you may build around it, and losing it can mean immediate elimination depending on the victory mode.

Detector Tower

Cost
80 Fe · 35 Cu
Structure
180
Armor
Tier 15
Power
-20

The Detector Tower is an anti-stealth sensor: it reveals cloaked enemy units (Phantom, Ghost, Wraith and others) within a wide radius, so your units and towers can see and fire on them. Unarmed itself - a pure reconnaissance structure against the stealth meta. Requires a radar.

Experimental Works

Cost
300 Fe · 215 Cu · 255 Ti
Structure
450
Armor
Tier 13
Power
-80

The experimental works is the most expensive but most powerful production facility: giant mechs, cloaked vehicles and EMP tech roll off the line here, and it also unlocks the cloaked ghost sniper in the barracks.

Mech Factory

Cost
190 Fe · 80 Cu
Structure
350
Armor
Tier 13
Power
-50

The mech factory produces the entire mech line - from the light scout to the heavily armored Titan mech to the rocket-launcher mech.

Siege Tower

Cost
130 Fe · 80 Cu · 55 Ti
Structure
220
Damage
62 at 340
Armor
Tier 15
Power
-35

The Siege Tower is a long-range defensive gun: its enormous range outreaches every siege weapon (artillery, MLRS, Railgun Mech), taking out enemy siege equipment before it reaches the base. Its blind spot is close range - it cannot hit targets right in front of it, so infantry and fast melee attackers counter it. Requires a technology center.

Flak Tower

hits air
Cost
110 Fe · 55 Cu
Structure
300
Damage
30 at 340
Armor
Tier 15
Power
-25

The Flak Tower is stationary anti-air defence: it fires ONLY at flying targets, but does so quickly and with the longest range of any tower - attackers are under fire long before their own weapons can reach it. Against ground troops it is completely helpless and needs other towers beside it. Requires a Radar.

Airfield

Cost
150 Fe · 70 Cu
Structure
400
Armor
Tier 13
Power
-50

The Airfield is the runway for the Fighter Jet - and for nothing else; every other Steel Union aircraft lifts off from the Helipad. The jet is by far the fastest thing in the game, but it carries only a few shots and returns here after every attack to rearm and repair. The runway costs accordingly in money and power.

Gun Turret

Cost
90 Fe · 35 Cu · 15 Ti
Structure
240
Damage
44 at 250
Armor
Tier 15
Power
-30

The gun turret is the heaviest stationary defense: its gun reliably punches through vehicle and mech armor, but struggles against individual infantry.

Helipad

Cost
190 Fe · 85 Cu
Structure
350
Armor
Tier 13
Power
-40

The Helipad is the Steel Union air base: Attack Helicopters and Sky Scouts launch from here. Both carry a limited supply of ammunition and return here to rearm and repair - without the pad the air force stands still. The Fighter Jet, by contrast, needs the long runway of the Airfield.

Listening Post

Cost
140 Fe · 70 Cu · 30 Ti
Structure
200
Armor
Tier 13
Power
-30

The Listening Post does not shoot. Instead it reports enemy units far beyond the fog and marks their rough position on map and minimap - as contact blips, not as recognisable units. Several enemies close together show up as a single blip. Requires a Radar.

Wall

Cost
25 Fe
Structure
550
Armor
Tier 20

The Wall is built as a LINE: the 1st click sets the start, then you drag the wall line and a second click builds it; Shift+click sets a corner and keeps going. Each segment starts at nearly 0% HP and grows over a few seconds - a wall thrown down in front of an enemy is vulnerable at first. Very high armor (concrete): small arms barely scratch it, only siege cracks it. Blocks paths and channels attacks. Gates and towers can be placed into a wall, seamlessly replacing the segment.

MG Nest

Cost
60 Fe · 20 Cu
Structure
160
Damage
14 at 245
Armor
Tier 15
Power
-15

The MG nest fires fast and often - ideal for wearing down advancing infantry early, but almost useless against vehicles and mechs.

Power Plant

Cost
80 Fe
Structure
250
Armor
Tier 13
Power
100

The power plant produces energy for the base - without enough energy, production and buildings run slower. Upgradeable with turbine upgrades at the technology center (two levels, +50 energy per power plant each).

Radar

Cost
70 Fe · 30 Cu
Structure
200
Armor
Tier 13
Power
-75

The radar has two jobs: it unlocks the minimap, and within its radius the fog veil lifts over ground you have already explored - enemy units there become visible too. It does NOT reveal territory you have never scouted. Late in the research tree comes the choice: extend that coverage across the entire explored map, or remove your own forces from all enemy long-range detection.

Missile Silo

Cost
400 Fe · 255 Cu · 340 Ti
Structure
550
Armor
Tier 15
Power
-80

The missile silo is the ultimate superweapon: after about 4 minutes of charging, any point on the map can be targeted - the missile hits EVERYTHING in the blast radius, including your own and allied units. Recharges automatically after every launch.

Rocket Battery

Cost
170 Fe · 95 Cu · 60 Ti
Structure
240
Damage
34 at 400
Armor
Tier 15
Power
-40

The Rocket Battery engages targets at even greater range than the Siege Tower. It fires a staggered salvo of three rockets per target that barely scatter even at full distance - but it reloads slowly. Like the Siege Tower it is blind up close. Requires a Technology Centre.

Refinery

Cost
100 Fe
Structure
400
Armor
Tier 13
Power
-25

The refinery processes ore into resources and comes with a harvester on construction. Harvesters deliver exclusively to the refinery - the closer it sits to the ore, the shorter the harvester trips and the more harvesters can work efficiently side by side.

Sniper Tower

Cost
75 Fe · 25 Cu · 15 Ti
Structure
180
Damage
45 at 260
Armor
Tier 15
Power
-20

The sniper tower sees and shoots farther than any other defense tower - deadly against infantry, especially anti-tank soldiers, but of little use against vehicles.

Heavy Foundry

Cost
420 Fe · 275 Cu · 325 Ti
Structure
520
Armor
Tier 13
Power
-110

The Heavy Hall is the second tier beyond the Experimental Works and thus the Steel Union's most expensive build gate. The Blast Furnace is built here.

Silo

Cost
100 Fe
Structure
300
Armor
Tier 13
Power
-5

The Storage Silo increases storage space - all three ores share ONE pool. The command center and refineries provide a base capacity. Once the pool is full, loaded harvesters stay docked and wait (the economy stalls rather than wasting surplus); copper and titanium together may only occupy 60% of it, so there is always room for iron. Costs only iron and is quick to build.

Technology Center

Cost
150 Fe · 85 Cu · 25 Ti
Structure
250
Armor
Tier 13
Power
-60

The technology center is the base's research forge: upgrade levels for energy, infantry, vehicles, mechs and air are researched here. A completed level takes effect immediately and on ALL of your units - including the ones built long ago.

Gate

Cost
55 Fe · 15 Cu
Structure
520
Armor
Tier 20

The Gate is built as a LINE like the wall (1st click start, 2nd click end, Shift for a corner) - as wide as you need. It lets your own units pass: each segment sinks into the ground when a friendly unit is near, and stays shut while an enemy stands beside it - so your wall line stays open for you but sealed against attackers. Built over an existing wall, it replaces those segments. Very high armor like the wall; each segment grows up from ~0% HP while building.

Vehicle Factory

Cost
250 Fe
Structure
300
Armor
Tier 13
Power
-50

The vehicle factory is the economic and military backbone of the base - it builds both harvesters for resource mining and the entire wheeled and tracked vehicle line.

Workshop

Cost
200 Fe · 85 Cu · 25 Ti
Structure
350
Armor
Tier 13
Power
-50

Vehicles and mechs can drive back to the workshop and dock to be fully repaired step by step (costs resources, proportional to the damage healed) - combat units even retreat to it automatically at low health.

Twin Cannon

Cost
150 Fe · 70 Cu · 35 Ti
Structure
320
Damage
50 at 270
Armor
Tier 16
Power
-45

The Twin Cannon is the heavy version of the Gun Turret: two barrels, double the output and a damage curve that only pays off against heavy armour. Against light vehicles and infantry it is wasted money - but it stops heavy tanks where a single Gun Turret gives way. Requires a Technology Centre.

Nothing found.
