They heal damage fully when resting in fungus, while other units usually must return to a base to completely repair. The Xenoempathy Dome Secret Project allows all your units to move as natives through Xenofungus, while the Pholus Mutagen Secret Project confers native combat bonuses on all your units. Mounting a successful attack on a well-defended base requires foresight and planning. First, a wise leader includes a diverse mix of offensive and defensive units in an invasion force. Defensive units can protect against counterattacks, and can convert to garrison duty once you conquer the target base.
Fast rovers can scout ahead and sweep enemies out of open areas.
Artillery can cut reinforcement routes by bombarding roads, reduce the strength of base defenders, and keep damaged units from repairing. You must destroy nearby sensors if you expect to take a well-defended base. Air power often proves the most straightforward tool for this task-use your needlejets to scout the area around a target and take out the sensor with bombing runs. If your jets don't succeed on the first try, postpone your main thrust until they do. These units can bombard terrain enhancements such as mines and farms, reducing the resource production of the target and starving out the populace.
