Colony Siege

Colony Siege combines the best of RTS and tower defense, including base building, mazing, and unit physics. Use shockwaves and spring traps to propel enemies into cliffs, lava, and other hazards. Build mechs, tanks, and other mobile units. Decimate massed enemies with air, missile, and orbital strikes. Expansive, non-linear campaign supports single player and 2 player online co-op. 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.
