20XX is an action-platformer built to play like Mega Man X and replay like your favorite roguelikes. The goal is to produce a game that's co-op friendly and highly replayable without sacrificing tight, satisfying action-platformer gameplay. It's targeting Windows first with plans to port to Mac/Linux post-release. (Maybe even consoles!)
Replayability is one of our core goals with 20XX; keeping the experience fresh is important to us. You get to choose from two completely different characters with their own playstyles. You get to play through entirely different levels every time you play -- the challenge set constantly shifts and you'll have to adapt to whatever the game throws at you.
