Units
All units fight from distance and hovering over a human will display its range. Each unit has its own preferred height compared to the enemy and will receive increased bonuses when attacking from their preferred height.
All units have an Oxygen maintenance cost that scales with the game difficulty. Units received as reinforcements during a mission do not have maintenance.
Iris
During all missions except tower defense Iris will be playable as a special unit. Iris can gain various passive and active skills via the Book of Insight. If she is killed on Expedition mission the mission fails. If she is killed on City Building missions she can be resurrected at the Citadel at the cost of 100 Oxygen. Resurrecting Iris is instant on Story and Easy and takes 15 seconds on Normal, 45 on Hard and 120 on Extreme.
Trainable units
The number of units that can be trained is limited by the Military Capacity, which starts at 10 and is increased at the Citadel. A rally point can be set by selected by selecting a building that produces units and right-clicking where newly recruited units should move. The time it takes to train a unit scales with game difficulty.
Each time a unit hits attacks, it gains experience. After it gains enough experience it becomes a Veteran and gains +20% Attack Damage and -15% Attack Cooldown. Each unit also has one upgrade in the building they're recruited from and one skill in the Book of Insight.
The Partisan is only available in Skirmish, Endless and Sandbox.
