Revision - the xol - ZeroSpace Wiki

The Xol are the fourth main faction of ZeroSpace, a civilization of autonomous robotic consciousness brought to the brink of extinction by the dark crusade of the Legion of Truth. Their motto is "For Purpose. For Survival." Though fiercely individualistic, they are united by a single imperative: survival.

Their bodies are shells of liquid metal and their minds are older than any living empire. As the tide of annihilation turns against them, they bring the most advanced robotics technology in the galaxy to bear and reshape their armies in the middle of a fight.

How They Fight

Trait	Effect
Merge	Combine simple units into far greater forms, then split them back apart when the situation changes.
Reconfigure	Reshape the whole army mid fight to answer whatever threat appears.
Outtech Everyone	The Xol field the most advanced robotics technology in the galaxy.

Commander

The named Xol commander is Anrubic. See Heroes and Commanders for how commanders are used across the modes.

Anrubic costs 220 Hexite, carries 175 health behind 175 shields, and fights the way the faction does: it can grapple enemies and merge with other Xol units to augment its own abilities. Its Xyther Shield Wall cooldown was cut from 90 seconds to 30 on August 11, 2026.

Forces

The official faction page shows four sample units and says the full list is coming later. A community-maintained catalogue current to August 26, 2026 covers 11 Xol units and 9 structures, the smallest roster of the four main factions, which is what the merge system trades away: fewer distinct bodies, more ways to recombine them.

Unit	Role	Cost	Supply	Health and Armor
Roller	Short range unit that folds into a sphere when not firing, doubling its move speed. Ordered as a pair	50 Hexite for two	1 each	80, Light armor
Spectron	Ranged unit that charges its shot to double damage out of combat and attacks ground and air	25 Hexite, 50 Flux	2	120, Light armor
Xyther	Melee unit whose shield takes reduced damage from large hits, ground targets only	75 Hexite	2	150 plus 100 shields, Medium armor
Defiant	Melee unit that gains energy when attacked, then spins for full attack damage to everything around it	150 Hexite, 50 Flux and 2 Xyther	4	500, Heavy armor
Echo	Light harassment flier that spawns weaker echoes of itself when attacking	50 Hexite, 50 Flux and 2 Rollers	2	125, Medium armor
Synapse	Flier that heals nearby units 8 a second on contact and can Overclock allies for +35% damage and move speed	50 Hexite, 150 Flux and 2 Spectrons	4	250, Light armor
Gravitron	Slow siege unit that lands and uses Reverberate to slow enemy movement and attack speed nearby	125 Hexite, 100 Flux and 3 Rollers	3	200 plus 200 shields, Medium armor
Havoc	Large rolling transport that carries up to 8 Rollers	200 Hexite, 200 Flux	4	400, Medium armor
Eradicator	Heavy artillery that hits up to four targets at once and can hurl 5 nearby Rollers, Overclocking them on landing	125 Hexite, 250 Flux and 3 Spectrons	6	1,000, Heavy armor
Xol Harvester	Flying flux harvester, respawning 60 seconds after it dies	175 Hexite	None	400, Medium armor
Scouting Drone	Light flying scout, capped at three	25 Hexite	None	75, Light armor

Merging and Reconfiguring

Five Xol units are not built from scratch. They are assembled out of units already on the field, so a Roller or a Spectron is both a fighting unit and a component you are banking for later.

Merged Unit	Built From	Extra Cost
Defiant	2 Xyther	150 Hexite, 50 Flux
Echo	2 Rollers	50 Hexite, 50 Flux
Synapse	2 Spectrons	50 Hexite, 150 Flux
Gravitron	3 Rollers	125 Hexite, 100 Flux
Eradicator	3 Spectrons	125 Hexite, 250 Flux

Unmerge runs the process backwards. It was free to use and available every 20 seconds after an August 11, 2026 update, down from 5 power and a 60 second cooldown, which made splitting a merged unit back into its parts a routine mid-fight decision rather than a last resort. The same update let Replicate work on molten units at twice the usual power cost.

The Molten Core adds a second layer on top. Its energy pool upgrades one unit type at a time, and each upgrade rewrites what that unit does rather than just raising a number. A molten Roller loses its weapon but explodes on contact, damaging and slowing enemies. A molten Xyther rebuilds itself when destroyed, on a 120 second cooldown. A molten Spectron fires a slow projectile that deals area damage. A molten Echo creates a hallucination on attack every 20 seconds, lasting 60 seconds. The Core regains energy when an enemy dies on top of it and damages anything that walks over it, and since August 11, 2026 friendly Legion conduits can recharge it and units can walk across it.

The World Forge is the wider version of the same idea: pick 3 of its 6 upgrades, take each to 2 ranks, and every Xol army unit benefits, with units standing near the Forge getting double the bonus.

Structures

Xol extractors are unusual in that the World Engine builds and rebuilds them without being told to. The Gyroforge, Spectral Foundry and Xyther Assembler each open tier 1 mercenary hiring, the Molten Core tier 2 and the World Forge tier 3.

Structure	Role	Cost	Health
World Engine	Mining outpost that raises extractors on a hexite patch, upgradeable to attack	400 Hexite	2,500
Extractor	Hexite extractor, built and rebuilt automatically by the World Engine	Built by the World Engine	330
Power Core	Xol supply structure, providing power	50 Hexite	250
Gyroforge	Base unit production	100 Hexite	1,000
Spectral Foundry	Base unit production	100 Hexite	1,000
Xyther Assembler	Base unit production	100 Hexite	1,000
Molten Core	Unlocks tier 3 Xol units and mercenaries, and upgrades individual unit types from a limited energy pool	50 Hexite, 25 Flux	1,250
Resonator	Defensive structure that takes its behaviour from whichever unit is fed into it	150 Hexite	600
World Forge	Holds 3 of 6 army-wide upgrades, each with 2 ranks, doubled for units standing near it	100 Hexite, 100 Flux	1,000

Balance Since Launch

The Xol shipped as the newest faction and have seen the heaviest tuning. The figures above describe the August 26, 2026 data release.

August 1, 2026	Terrain	Xol and Grell can now build on each other, on Power Fields and biomass alike
August 11, 2026	Unmerge	Cost cut from 5 to 0 and cooldown cut from 60 seconds to 20
August 11, 2026	Replicate	Now usable on molten units, at twice the power cost
August 11, 2026	Molten Core	Energy can be recharged by friendly Legion conduits, and the Core can now be walked over

August 11, 2026	Gravitron	Move speed raised from 300 to 400 and its aura radius from 13.5 to 15
August 11, 2026	Synapse	Healing buff cut from 10 to 8 health a second
August 11, 2026	Echo	Damage bonus changed from +100% against harvesters to +50% against medium armor when the harvester armor type was retired

August 11, 2026	Overclock	Move speed bonus raised from +35% to +150
August 14, 2026	Buildings	Fixed Xol buildings that could not be prequeued before their requirements were met

Beta Status

The Xol became playable for the first time at the Early Access launch on July 20, 2026, and the published roadmap labels them a beta faction for the Early Access period. They can be played in the campaign, custom games and the Galactic War, but the studio holds them out of ranked matchmaking until community balance testing settles. They still appear as a filter option on the official standings page alongside the Protectorate, the Grell and the Legion of Truth.

Because their units merge and reconfigure, Xol army composition is less fixed than the other factions, and balance updates during Early Access have repeatedly adjusted how their buildings and prerequisites queue.
