Here's an interesting little rumor. Gearbox Software, the developers of Borderlands, Aliens: Colonial Marines, and Brothers in Arms, are currently in the very early development stages of a new game.
The rumor, coming from a member of the IGN boards, states that the the developer is working on a new FPS IP that utilizes the Unreal 4 engine. The user also states that the game is multi-platform, but the rumored information comes specifically from a Wii U version.
Could this unknown IP be one of the titles set to be announced at the third-party Nintendo Direct in a few weeks? Since it's in early development, it probably won't be featured, but maybe it'll be announced or mentioned?
