Hi there! Space Battalion Alpha has just been released!. It's a short and simple shoot'em up. It's meant to be easy. And it's on sale for a few days!
It has three modes (Campaign, Level Select, and Survival). In Campaign mode you'll fight your way through ten levels. Level Select allows you to play any previously cleared level (or boss) and Survival will keep you fighting against an increasing wave of enemies while trying to reach the best score.
All modes are up to 4 players in couch coop!
