34. VC5 Arc Rifle

Killzone 2

You know a weapon's good when you can only pick it up one time throughout the entire game. You can't even use Killzone 2's Arc Rifle in multiplayer, or in Killzone 3 at all, despite it being wielded by specialized Helghast troops. Ammo is scarce, but when you can chain one electrically-charged shot between every enemy in spitting distance, it doesn't really matter, does it?
