Protocol Zero
A space-themed tower defense game — command an orbital station against endless waves.
Protocol Zero is a space-themed tower-defense game where players command a lone orbital station against relentless waves of hostile forces. Built in Godot 4 with GDScript, it delivers smooth, responsive action tuned specifically for mobile devices.
Players strategically place and upgrade defensive turrets, manage limited energy resources, and adapt their loadout as enemy types escalate — every wave demands sharper positioning and faster decisions than the one before.
Polished with intuitive touch controls, dynamic difficulty scaling, particle-rich visual effects and an original sci-fi soundscape, the game balances quick pick-up-and-play sessions with deep strategic replayability.
