Colony Siege is a real-time strategy, survival, and base defense hybrid. Battle in a wide variety of environments to defend the last human colonies from two unique threats. Survive alone or with a friend as you progress through a non-linear campaign.

Defend Your ColonyWhether fighting the Xenos or the Riven, no colony building is safe from attack. While protecting the colony Citadel is your primary objective, the enemy will not discriminate when it comes to attacking your colony. Defend against the relentless biomechanical xeno swarm as well as the corrupted Riven that were once human. Both enemy factions behave differently and require different tactics.

Use Towers and Design MazesDefend with powerful towers that automatically form walls when placed near each other. Use unique traps to slow, impale, burn, or bombard the enemy. Build and command mobile ground units. Strike the enemy with satellite-powered attacks, long-range missiles, commander abilities, and fighter sorties. Defensive towers and barriers automatically generate a laser fence when constructed close together, allowing your mobile units passage while restricting enemy movement.
