At the recent eastern Penny Arcade Expo (or PAX East 2015, if you prefer), a developer named Batterystaple Games caught some attention with a title which Tech Times is calling "the Mega Man X sequel Capcom should have made."
Interestingly enough, despite culling influences from a gunning blue robot to a beam saber-wielding red robot, the group are calling their title "20XX," and have posted the following trailer to Steam Early Access:
20XX is a game built to feel like Mega Man X, but with random levels, random powerups, permanent death, and multiplayer. The game uses a procedural level generation algorithm that pieces together levels from a certain number of mechanics at a time; it switches rapidly between playing like an action game and playing like a platformer, mixing precision jumping with fevered combat.
Add in permadeath and over 100 powerups to find in between agonizing deaths and you've got hours of nail-biting jumping-and-shooting goodness on your hands.
In addition, the game will also contain a co-op mode available locally or online.
Thanks for the tip, Michael S!
