A trailer for the upcoming PSP version of BlazBlue: Continuum Shift Extend, releasing in Japan this May 31. The 2D fighting game BlazBlue: Calamity Trigger was once again developed by Arc System Works (of Guilty Gear fame). It was initially released for the arcades in November 2009, and later ported on the PlayStation 3 and Xbox 360 consoles, with a North American release handled by Aksys Games. Additional versions for even more consoles followed throughout 2012. The game's opening animation was created by the anime studio Gonzo, as they did with the 2008 prequel BlazBlue: Calamity Trigger.
