About Astro Battlers TD
Astro Battlers TD is a lane-defense game about kids who land on a promising planet only to find it threatened by dangerous Astro Balls. You place traps, choose which lane to defend by moving the kid, and fend off enemy waves with upgrades, Skill Cards and powerful attacks.
Defend the lanes
You can plant Turrets, Popcorn Machines, Bombs, Walls, Spikes, Moving Platforms and Mystery Boxes. Spend Popcorn to buy more traps and update points to upgrade them. Random Wave Rewards make each run different, while stars let you buy Skill Cards to shape your playstyle. Use the Laser and Snowball ultimates to clear waves, or call on your buddies for help.
Enemies and customization
The game features over 400 enemy variations, including squishy and slimy Astro Balls, armored space drillers, exploding enemies and big bad worms. You can customize your kid’s hair, clothing colors, skin tone and boots; these options are accessible without payment. Hilarious sounds and graphics are also part of the game.
Game modes
- Normal levels: Collect Stars to progress your Skill Card build. Each level has a preset board state and its own enemy waves.
- Hard levels: Play levels like the normal ones, but at a much higher difficulty.
- Endless Mode: Face waves that never stop.
