The way the Ratchet & Clank wiki capitalizes words has changed; therefore, this article should be checked, and, if necesary, capitalization should be fixed. For more information, see the forum.
Stock up on ammo, and walk down the path. Take out the Blade Balls and DZ Strikers with the Dual Vipers, and keep going until you reach the Stalker Turret. Hide behind the wall that is slightly in front of it, and launch an EMP. If one of your Battle Bots gets killed, just revive it and try again. Eventually, it's shields and blasters will go down, so spray it a couple of times with the Magma-Cannon and it should be destroyed. Take out any more enemies that appear and then use another EMP on the two platforms. Jump across and launch onto the cliff using the pad to complete the challenge.
