This is an extended version of Cyberblutch's Rebirth Beta 01 Mod. The extensions were either released by Cyberblutch himself (like the monkeys) or taken from a fanmission that he had contributed a model to (like the rumbler) or are modifications by other parties. The current version is Beta 05, see the homepage for a download.
