IGN Previews Supersonic Acrobatic Rocket-Powered Battle-Cars

IGN writes: "It’s entirely possible that you’ve played some of Psyonix’s handiwork and never really heard of the developer. Its first product wasn’t really a game, per se, more of a full mode contained within another developer’s game — specifically Unreal Tournament 2004. UT2K4’s Onslaught mode was originally going to be developed as a stand-alone mod, but series creator Epic Games was so enamored of the addition that it contracted Psyonix to develop the mode to ship as part of the full retail package".
