If you bought the game Prototype for PS3, you not only have a mandatory install but a chance it will fail. If this happens and you do have enough free hard drive space for the game (despite what it might tell you), the workaround (until the inevitable patch) is to add or remove about 700MB worth of files. This can be done by downloading or deleting demos, videos, etc. If this sounds familiar, nearly the same thing happened with Ratchet and Clank Future: Tools of Destruction some 20 months ago. As we said at the time: It's not a bug, it's a meta-game...
