"Just to clarify for those asking, this particular video was captured with footage from the PS3 version of the game," Rockstar Games said on its website.
The nearly five-minute video (below) details the game's new three-protagonist system and introduces players to a range of new locations, items, and activities. The video was captured entirely from in-game footage.
GTAV launches worldwide September 17 for Xbox 360 and PlayStation 3. PC and Wii U versions are "up for consideration," while Rockstar is reportedly hiring programmers to bring its "latest titles" to PC.
