Ratchet & Clank: Quest for Booty is a 3,181MB download, we can report. Because we're downloading a review copy and have nothing better to do in the meantime.
Insomniac Games' latest PS3-exclusive is due out this Thursday, 21st August, and will cost GBP 9.99 on the PlayStation Store.
If you prefer, you can also buy it on Blu-ray in Europe from 12th September, and you won't have to pay a penny more. Unless you tell them to keep the change.
Quest for Booty is a 3D platformer that picks up where Ratchet & Clank: Tools of Destruction left off, with Clank off with the Zoni and Ratchet on a mission to save him.
