There's a new Assassin's Creed game coming, and it'll launch this summer. Publisher Ubisoft announced Assassin's Creed: Memories today, an iOS card-battling game which is being developed by mobile studios GREE and PlayNext.

The game focuses on customization, time-traveling, and alliances, encouraging you to create your own Assassin and team up with people who complement your play style. There's a strong focus on making your own character and strategy, according to GREE vice president Eiji Araki: "The card battle genre is all about being able to evolve and grow great heroes and this franchise has created some of the most epic characters in gaming today." You will visit time periods from past Assassin's Creed games, like the American Revolution and Renaissance Italy, but Ubisoft promises that there will be new areas and times as well.

Perhaps the most interesting part of the announcement is that Memories will feature a full multiplayer mode with up to 20 players on each side. Right now, Ubisoft hasn't said anything more about the mode. There will also be a "rich single-player experience," the publisher promises.

The game launches for iPhone, iPod Touch, and iPad later this summer. The next console version, Assassin's Creed Unity, is coming on October 28 for Xbox One, PlayStation 4, and PC. Is Memories enough to hold you over until Unity launches? Let us know in the comments!
