Ratchet & Clank: Full Frontal Assault

Ratchet & Clank: Full Frontal Assault uses the camera angles, weapons and third-person Ratchet gameplay used in previous versions, while adding a new tower defense element. It features five levels set on three different planets. The game allows players to play as Ratchet, Clank (in either his Giant Clank or normal forms), or Captain Qwark. This title also features the ability for co-op play, both on and offline. Source: Wikipedia, "Ratchet & Clank: Full Frontal Assault", available under the CC-BY-SA License.
