Ultra Street Fighter IV is the last iteration that SF4 got, and the ultimate edition that will provide you with the full roster of 44 characters! It’s a must-have for Street Fighter fans, and the gameplay is quite more challenging and advanced than SFV‘s accessibility.
The original Street Fighter IV was released back in 2008, and up to Ultra Street Fighter IV’s release in 2014, a lot of new characters were added:
Super Street Fighter IV – 2010 – Adon, Cody, Dee Jay, Dudley, Guy, Hakan, Ibuki, Juri, Makoto, T. Hawk
Super Street Fighter IV: Arcade Edition – 2011 – Evil Ryu, Oni, Yang, Yun
Ultra Street Fighter IV – 2014 – Decapre, Elena, Hugo, Poison, Rolento
It’s also worth noting, that if you have save data from Street Fighter X Tekken on your device, you can unlock alternate costumes for all USF4 characters!
