Adder is a rogue-lite 2D action platformer that challenges players to manage random weapons, ammo, and abilities while fighting through hordes of zombies on procedurally generated levels. The map resets once the player dies, but new content and colony upgrades can be unlocked on each run. It takes place in an early 2000s United States with intentionally ambiguous geography. The player controls an expendable survivor, drawn from the population of the colony. The end goal is to formulate a vaccine with research data gained by killing a boss from each corner of the map.
As a rogue-lite, Adder’s design philosophy is to give the player the tools to complete the game from the beginning, with the only barrier to winning being their own skills. Each run is a new experience with randomized elements.
