EF-12- Fighting Game Maker is now available on Steam, offering a Windows fighting game with an unusual focus on customization. In addition to allowing you to brawl with opponents, the game includes the ability to import custom content created by yourself or others, saying this requires no programming knowledge to add new characters and stages. Along with the game they offer a playable demo allowing you to check out gameplay, though this does not support these import functions. According to Steam News, "Also, if you are keeping an eye on the guide's section. We have added a series of guides on how to work different aspects of editing and customizing EF-12." Here's a trailer.
