Seeing the SSB, PSASBR and PXZ threads all empty and dead, I thought it'd be a good idea to create a new thread just for crossovers in general. With more than one subject to rely on, the thread will more likely be lively. Now, on to the starting topics:
Super Smash Brothers
The next installment of the series will be revealed next E3 along side other big titles from Nintendo.
Playstation All Stars Battle Royale
The new DLC, Kat (Gravity Rush), Emmett Graves (Starhawk) and the Heavenly Sword/Wipeout stage will be released next month free for two weeks.
Project X Zone
A localization of the game will reach America, Europe and Australia this summer with translated text and unaltered content.
Shin Megami Tensei X Fire Emblem
A new collaboration between Atlus and Nintendo will come to the 3DS soon.
Project Versus J
A new open-area fighting game made for Jump's 45th and V-Jump's 20th anniversaries was recently announced that so far includes Goku (Dragon Ball), Luffy (One Piece) and Toriko (Toriko) with more to be revealed.
