Ratchet & Clank: Full Frontal Assault

In this installment of the popular intergalactic franchise, Ratchet & Clank, along with the galaxy's own Captain Qwark, must stop a sneaky villain from Qwark's past. This game is unique in the series, in that it incorporates elements of 'tower defense', which the player must continually defend the QForce base from invading enemies. Various weapons such as missile turrets and plasma mines can be used to slow down the invaders, along with barriers that force the enemy to destroy it before proceeding. Along these lines, the player must complete the objectives on each level while keeping their base up & running.
