Ouroboros

Body as a weapon

Ouroboros is a PC wave-based action game about controlling a snake whose body is both its weapon and its deck. Food you eat adds a working body part: Fang Turrets shoot, Venom Glands trail poison, and Blast Sacs smoulder. Each part has a passive effect and a one-time detonation. You steer around enemies while deciding whether to grow stronger or bite off part of your body to escape.

Longer bodies can deal more damage, but they’re harder to steer and can block your own movement. You can coil around a boss to pen it in, for example, but the coil can trap you too. Biting a body part detonates it where you choose, but you have to stand still to do it. Alternatively, you can drop your tail as a live charge, move away, then set it off when an enemy is standing on it.
