Colony Siege: A Tower Defense RTS Hybrid That’s Out of This World

Colony Siege isn’t your average tower defense game. This thrilling hybrid blends real-time strategy (RTS) elements with the satisfying crunch of tower defense, creating a uniquely engaging experience. Forget static defenses; here, you’re a colony architect and battlefield commander rolled into one.

The core gameplay revolves around defending your precious colony from relentless waves of Xeno and Riven enemies. These factions, each with unique behaviors and weaknesses, demand diverse tactical approaches. Build a network of automated defensive towers that cleverly form laser fences when placed adjacently, creating mazes to funnel and trap your foes. Supplement these with a devastating arsenal: spring traps launching enemies into fiery pits, shockwaves scattering hordes, and powerful orbital strikes raining destruction from above.

But don’t just rely on static defenses. Command a fleet of mechs, tanks, and other mobile units, strategically deploying them to exploit gaps in your maze-like defenses. The persistent progression system lets you upgrade your arsenal, unlocking new towers, traps, units, and devastating strikes with each mission.

The expansive, non-linear campaign unfolds across a starmap, offering branching paths and replayability. Whether you tackle the challenge solo or team up with a friend in seamless two-player co-op, the strategic depth and variety of environments—from alien planets to sprawling space stations—ensure countless hours of thrilling gameplay. Prepare for an epic siege!
