It's slated to be an "asymmetric multiplayer shooter" and it apparently includes jetpacks and at least one big monster. Game Informer's February issue will have some of the first details on the game.
The sci-fi multiplayer-focused shooter pits a four-player crew of alien hunters against a separate player-controlled monster that grows larger and more powerful over the course of matches. Each hunter features its own unique items and abilities, and while the monster may be outnumbered, its size and an assortment of devastating attacks make it a more than formidable foe. Like Turtle Rock's previous titles, Evolve is being built with variety and replayabilty in mind; the result is a novel mix of cooperative and competitive multiplayer elements that's unlike anything we've played before. Our exclusive hands-on time with the game's four-versus-one hunt mode left us with plenty to be excited about, and you can get all the details in this month's issue.
The game will be published by 2K Games. Hopefully it pans out for them since they paid $10.8 million for the IP as part of the auction of THQ in 2013.
History tells me only team vs team multiplayer shooters really do well, i'm always interested to see what people can come up with though.
