Activision has had to think up a workaround for the newly released Prototype, apparently it's not so friendly to PlayStation 3's when trying to install.
The game refuses to believe you have enough available space to install necessary files, but Acti's workaround suggests that altering that by 700MB should help convince the game.
"We take this issue very seriously and are working to resolve this issue as soon as possible. We apologize for any inconvenience this may cause," Activision said.
You know we've reached the future when a piece of tech calls you a dirty stinking liar. By installing another game, a demo or even a HD video trailer of something then you could well be on your way as Alex Mercer. Naturally they expect to release a patch soon enough.
Remember: 700MB +/-
