Fire Biu

Fire Biu is a cheerful pixel-art tower defense game that runs entirely in your browser. Pick one of three soldier classes, place them on the grass, and upgrade them between automatically advancing waves. Each of the three campaign levels has its own route network, starting budget, and enemy mix, so you will need to adapt your build. Earn coins from defeated vehicles, spend them on rifle soldiers, rocket launchers, or snipers, and choose target priorities to stop leaks. Clear a level to earn up to three stars based on remaining health, unlock the next map, and replay for a better result. Keyboard and touch controls are both supported.

How to play

• Click or tap a soldier card, then click a grass tile to place it.
• Click a placed soldier to upgrade, sell, or change its target priority.
• Waves start automatically. Press Space to start the next wave early.
• Use the speed button to cycle 1×, 2×, 3×, and 5×. Press Esc to pause.
