Bulletail

Your tail is your ammo Bulletail is Snake with a gun. Every bullet you fire comes out of your own tail, and the only way to get it back is to eat more. Shoot too much and you shrink. Shoot too little and the enemies close in. How it works - Every segment of your tail holds 10 shots. Every 10 shots you fire, you lose a segment. - Eat the bullets lying around the arena to grow. Each one adds a segment and 10 ammo. Kills sometimes drop more. - Getting hit costs tail. On Hard, every hit takes more than the last. - Run dry, run into yourself, or lose your last segment and the run is over. What you're up against - 8 enemy types, from simple chasers to shielders, teleporters, exploders, spawners and snipers that line up their shots - A boss every 10th wave: the Swarm King, the Tank Destroyer and the Speed Demon, each with its own attacks - 10 powerups like Rapid Fire, Multishot, Time Slow, Ghost Mode and Magnetism - 8 upgrades to build your run around. After each wave, pick one of three. Modes - Normal: survive as many waves as you can on Easy, Normal or Hard - Boss Rush: nothing but bosses, back to back. How long can you last? Also included - Steam leaderboards for every mode and difficulty - 19 achievements - Steam Cloud saves - Full controller support - 17 languages
