About Asteroid Sweep
Asteroid Sweep is a vertical shooter. Your ship fires automatically, so you only steer. Position it under falling asteroids to destroy them before they reach the bottom or hit you. Tougher asteroids need several hits on later levels.
How to play
- Drag across the board or use the arrow keys to move the ship.
- The ship fires on its own.
- Destroy enough asteroids before three get through.
Tips and strategy
- Park directly under an asteroid and let the bullets do the work.
- Prioritise the asteroid that is closest to the bottom.
- Do not chase small asteroids at the edge, they drift.
Levels, stars and XP
Finish a level to earn one to three stars and XP towards your player level. Replay any unlocked level to improve your stars. From level 151 the game enters endless mode, where each level is a remix of an earlier one with fresh colours and a slightly higher difficulty.
