Colony Siege (v1.20.1)

Colony Siege is a real-time strategy game that blends tower defense mechanics with dynamic base building, unit management, and physics-based combat. Set across a variety of alien worlds, moons, and massive space platforms, players must defend their colony’s Citadel against two hostile factions: the relentless biomechanical Xenos and the corrupted human Riven. Each enemy faction demands unique tactics, challenging players to adapt their defenses and strategies accordingly. The game emphasizes creative use of environmental hazards, such as cliffs and lava, where traps and shockwaves can be employed to devastating effect by propelling enemies into deadly terrain. The gameplay offers a rich mix of defensive and offensive options, including the construction of interconnected towers that automatically form protective barriers while still allowing friendly units to navigate through. Players can also build and command mobile units like mechs and tanks, and call in powerful air, missile, and orbital strikes to turn the tide of battle. The campaign unfolds non-linearly on a starmap, featuring dozens of missions with branching paths that encourage replayability and experimentation. Progression is persistent, allowing players to earn currency through mission objectives to unlock upgrades, new units, traps, and special abilities. Whether playing solo or teaming up with a friend in cooperative mode, Colony Siege offers a strategic and engaging experience that combines tactical depth with fast-paced action across diverse and visually striking environments.
