Cosmic Defense is a fast-paced tower defense game where you must hold the line against waves of enemies attacking through space routes. Build combat towers, combine their strengths, upgrade your defenses, and choose the right strategy for every map.
The game features multiple enemy types, including fast units, armored targets, stealth threats, and bosses. To win, you need more than just placing towers — you must manage resources carefully, upgrade at the right time, and adapt to every battle.
Each level demands better decisions and stronger tactics. Use the strengths of laser, cryo, tesla, and other towers, react to wave composition, and stop the enemy before they reach the end of the track.
How to play
Choose a level on the map and start the battle. During the match, place towers on available tiles, spend credits wisely, and upgrade your defense as the threat grows.
Watch enemy types carefully: some move faster, some can absorb more damage, and others require special counterplay. Combine towers to handle different wave compositions efficiently.
You can pause the game, change speed, and upgrade selected towers during a run. Your goal is to prevent enemies from breaking through and destroying the base. The better your perfomance, the higher your rating and progress.
