From the moment the concept leaked around this time last year, PlayStation All-Stars Battle Royale has been slapped with labels like "PlayStation Smash Bros". So, OK, fine, here you go. A bona fide Sony Smash Bros., courtesy of four Super Smash Bros. Brawl modders.
The modders -- ExorcistRain, Frusciante, KTH and Kingskull95 -- have delivered a Smash Bros. with all but one character from the PlayStation All-Stars roster -- plus some special guest stars. They didn't get Col. Radec of Killzone into the mod. But they did add Niko Bellic from Grand Theft Auto IV, John Marston from Red Dead Redemption, Lara Croft of Tomb Raider, Old Snake from Metal Gear Solid, Kazuya Mishima of Tekken, Tomba from, well, Tomba!, Isaac Clarke from Dead Space and Commander Shepard from Mass Effect.
That's a lot of value for the unbeatable price of free. See the link for loads of screenshots of these characters in action, plus more information on the mod.
