Ultra Street Fighter 4 will hit Japanese arcades later this month, Dengeki Online reports (via Siliconera).
Ultra Street Fighter 4 includes five new characters (Elena, Rolento, Poison, Hugo, and the recently unveiled Decapre), bumping the playable roster up to 44 combatants. The game also features an array of fixes and balance tweaks, along with new mechanics like the invincibility-extending Red Focus attack and an optional Double Ultra mode.
The arcade version of Ultra Street Fighter 4 will launch on April 17. Ports for the Xbox 360, PlayStation 3, and PC platforms are slated to arrive later this year at retail and as DLC for Super Street Fighter 4.
