The official PlayStation blog has some new info on the upcoming Ratchet and Clank: Full Frontal Assault.
While the game is returning to more core R&C
gameplay, Captain Qwark will still be available as a playable character throughout. The PSN game will contain five different levels across three planets, along with an online mode to be announced later, and lots of unlockable content including character skins and weapon upgrades.
There's also a new feature in the gameplay that Insomniac describes as "tower defense," which "will have you building and defending a base against invasions using your ultimate Ratchet & Clank
arsenal." That's all we've got for now, but presumably you'll be building or placing towers as you play, defending against invading waves of enemies. We'll hear more about Full Frontal Assault
before the end of the year.
