The hard to emulate "murder mystery visual novel adventure game" Danganronpa: Trigger Happy Havoc that originally saw release on PSP (later appearing on PS Vita where it also got a Western release) will launch on Steam on February 18. As a bonus the soundtrack "Despair in Stereo" will be included with every purchase during the first week on sale on Steam and there's also a 20 percent discount during that first week. That said the list price is perhaps a tad higher than you'd expect ($29.99)
Below is a series of screens from the PC version of the game.
