Having been the bearer of bad news earlier this month when he suggested that Unreal Tournament 3 might not make its release date, Epic's Mark Rein has now said maps have had to be cut from the PlayStation 3 version because the next-gen system can't handle them.
Speaking to IGN, Rein commented that the maps not in the PS3 release didn't sit well on the console "because the system didn't have the resources to produce a smooth gameplay experience."
Ouch.
It's not yet been made clear whether the same maps are set to be cut from the Xbox 360 release - itself expected at some point next year, but for now, the definitive version is looking to be the PC release.
