Revenge of the Titans.
Titan Attacks is an arcade shooter in the same vein as Galaga and Space Invaders, though Curve Studios says it includes "modern features, new strategies" as well as online leaderboards and an upgrade system. The game features over 100 levels, spanning five worlds. Puppygames' other creation, Revenge of the Titans, is deemed a thematic sequel that mixes real-time strategy and tower defense elements together.
Both Titan Attacks and Revenge of the Titans are available for $9.99 on Steam for PC, Mac and Linux. The Titan Invasion bundle will be Cross-Buy compatible on all three Sony systems.
