This is me phoning it in super late. Oooooo, look at the pretty trailer for Street Fighter x Tekken. Word on the street says Street Fighter x Tekken will feature 2-on-2 battles between four players and Tekken's bound system (aka ground bounces). There's actual game play footage, but it was boring in comparison to this rocking trailer with cinematics.
Based off of this trailer, Capcom has confirmed Ken, Ryu, Guile, Able, and Chuni-Li on the Capcom side and Kazuya, Nina, King, Marduk, and Bob on the Tekken side. According to an interview with Seth Killian on Eurogamer, it sounds like Street Fighter x Tekken will have a different feel than the ordinary Capcom versus game. Some things worth mentioning is the health bar situation and the tag in system. As far as the health bar goes, if one of the two characters dies, then it's game over regardless of the other character's health. For the tag in system Seth said, "You can just tag normally – it's pretty fast. But it's not completely safe...So you want to find situations where you can tag. One of the ways you can do that is by tagging in during a combo." If you want to read the entire interview with Seth Killian (and it's really good if you're looking for more information about Street Fighter x Tekken) you can check it out here. So yeah, I'm excited, but I'm very sad that Capcom has found another way to suck up all my free time...and my not so free time.
