The Clank Backpack in Resistance Fall of Man.
The Clank Backpack is an unlockable piece of multiplayer equipment. It features a backpack that looks exactly like Clank from Insomniac's Ratchet & Clank series, and the Gravity Boots from the same franchise as well. A wrench piece from Ratchet and Clank can also be unlocked with this armor later on.

The backpack is unlocked when the player earns 100 skill points.
