Revision 10

ZeroSpace is an army-scale strategy game, and its forces span more than 150 units and buildings across the playable Factions. Each faction has its own roster, from cheap expendable troops to heavy super-units, so the army you build depends heavily on who you are playing.

That figure held for months without a first party source behind it. An entity level count of the current build settles it: 149 units and 89 buildings are enumerated across the playable rosters, so the total clears 150 on either denominator. The store puts the shipped Early Access figure differently again, at over 90 unique units and heroes, which counts the versus roster rather than every entity in the game.

Veterancy

A system shared by all factions is veterancy. Units become more effective the longer they survive a battle, which rewards players who protect their forces and keep experienced units alive instead of trading them away. Combined with faction experience levels, this means a force that endures grows steadily stronger over the course of a fight.

Range of Forces

Unit design varies sharply between factions. The Protectorate favors durable, well-supported units backed by self-healing structures. The Grell lean on organic forces tied to their biomass. The Legion of Truth pairs powerful customizable tanks with swarms of cheap basic troops called thralls, and the Xol merge simple machines into larger ones mid fight. On top of the base rosters, six mercenary groups add specialized units you can mix into your army.

To keep big battles readable, units have generously sized hitboxes so they do not clump too tightly together. Large armies spread out on the field and read as the imposing forces they are, which makes it easier to follow what is happening as the fight grows.

On August 19, 2026 the studio moved a further twenty two units and structures onto the animation system already used by Commandos and Stingers: the Sentinel, Harbinger, Skrell, Exalted, Dark Disciple, Storm Bringer, Weaver, Shade, Asterion, Chronowarper, Shadow Leech, Pak'o, Saq'chi, Chas'ki, Heavy Trooper, Sharpshooter, Frog, Dinobot, Deadeye, Clakjaw, Harvester and the Protectorate Extractor. The studio reported large performance gains when many of them are on screen at once. Four of those names have since changed. The August 28, 2026 update recorded that unit names were revised for the Cha'Kru and the Endari, and the build that followed carries the Cha'Kru Cultist as the Pak'o, the Cha'Kru Rageborn as the Saq'chi, the Endari Drake as the Wyrm, and the night form of the Endari outpost as the Awoken Hollow. The list above uses the current names. Clakjaw is the spelling the build itself uses; the patch notes have also written it Clackjaw.

Buildings are part of the same picture, handling production, defense, and economy. For the leaders that head up these armies, see Heroes and Commanders, and for the upgrades and costs behind them, see Resources and Economy.

Named Units by Faction

The official faction pages show a sample of each roster rather than the complete list, noting that the full unit roster is still being added. The units named so far are:

The six mercenary groups field smaller rosters that you mix into a main faction army rather than play on their own:

The Endari count of seven includes two entries that are not hired like the rest: the Impaler, a short-lived alternate form the group's hero can take, and the Awoken Hollow, the flying night form of its mobile outpost. The other five are ordinary hires. These counts come from the current build data rather than from a published roster, and they will move as the build does.

Armor Types

Every unit and building carries an armor type, and weapons carry bonuses that key off it. There are six in the current build, plus a set of tags that are not armor types but behave like them for targeting.

Flyer and Massive are tags rather than armor types. Flyer marks an air unit for targeting rules. Massive marks the largest things on the field: the Legion Terror Tank, Dreadnought, Monolith and Emperor Projection, the Protectorate Strider and Sol Invictus, and the Valkaru Beast, which gained the tag on August 11, 2026.

Armor is also a number, held separately from the type. It subtracts flat damage from every hit, with a floor of 1 damage per attack, so it blunts fast weak attacks far more than single heavy ones. Three armor against ten attacks of 4 damage cuts 40 damage down to 10; the same three armor against one 40 damage hit saves 3.

Armour types matter for damage bonuses. An update during Early Access removed the separate Harvester armour type, moving harvesters and extractors onto Medium armour and retuning every bonus that previously keyed off the old type. That happened on August 11, 2026, and the reworked bonuses landed on six units: the Grell Skrell dropped from +150 percent against Harvester to +50 percent against Medium, and the Protectorate Ironwing and Predator, the Xol Echo, the Free Corsairs Raider and the Marran Pulse Skimmer were all converted to the same +50 percent against Medium.

Tiers

Units and buildings also carry a tier, which marks roughly where they sit on a tech path rather than how strong they are. The scale runs from Tier 0, the structures you place before any research, up to Tier 4, with half steps at 1.5, 2.5 and 3.5, and a separate Ultimate tier for endgame units and buildings. A Protectorate Supply Platform is Tier 0; the Titan sits at Tier 2.5.

Reading a Unit

The stat block on a unit is worth learning because it tells you what to compare between two options. These are the fields it carries:

The Protectorate Titan is a useful worked example, because it carries almost all of them:

Those numbers describe build ZS.c36778, current in September 2026, and they move with the patch cadence. The Titan was touched twice in a month. On August 11, 2026 its damage went from 7 to 8 and its bonus was changed from +100 percent against Medium to +25 percent against Light. On August 28, 2026 its anti air weapon lost range, from 15 to 14, and damage, from 24 to 20 a missile, and its two upgrades were consolidated onto one tier at 125 flux each.

Unit Index

Every unit in the versus roster has its own page. The tables below list all 87 of them, grouped by the faction or mercenary group that fields them. Figures describe build ZS.c36778, current in September 2026. Mercenary units carry no build time because they are hired at an outpost rather than produced, which is a property of how they reach the field rather than a gap in the data.

Protectorate

Grell

Legion of Truth

Xol

Mercenary Groups

The six mercenary groups are contracted partway through a match and folded into a main faction army. Their units are hired at an outpost, so none of them carries a build time.

Arandi Empire

Cha'Kru Kingdom

Endari

Free Corsairs

The Marran

The Valkaru

Infuse, Reanimate and Replicate

Three factions can act on a unit that already exists rather than build a new one, which is why every stat block carries three separate conversion prices. All three are paid out of the top bar power pool.

Not every unit is eligible for all three, and the tags on a unit say which apply. See Resources and Economy for how the top bar pool fills, and Update History for the dated record of the balance changes above.
