Our take on Siege of Centauri

The bounce point arrives when enemy traits require specific counters rather than general tower placement. Players must account for disabled defenses, area effects, and enemies that return after destruction, while also timing orbital abilities and unit calls during large waves.

What is Siege of Centauri?

Siege of Centauri is a tower defense game set during an alien assault on Earth's first interstellar colony.

Players deploy defensive structures, activate orbital abilities, and call units at selected moments to protect the colony. Missions form story-driven campaigns across the surface of Proxima Centauri, while Endless Mode sends continuous enemy waves and records leaderboard results. The Carpathia can be customized for individual missions, and towers have dozens of upgrade options, including effects that slow targets, leave burning areas, or spread corrosion between enemies. Alien machines use varied attacks and defenses, including units that disable defenses or return after destruction. A workshop supports creating, sharing, and downloading user-made missions.
