This weapon is essentially a chainsaw compacted into knife form so that it can be wielded with just one hand. Nevertheless, the Ripper inherits many of the qualities of its larger version. This weapon is good for a low-mid level melee player. The attack button can be held down and it will dismember anything in front of the player (much like a chainsaw or thermic lance), and its continuous cutting action means the Ripper ignores Damage Resistance and Damage Threshold. This makes it very good for handling multiple enemies or large, but slow, creatures.
When damaging some enemies, like mantises, red blood will be sprayed instead of green.
Xbox 360 Sometimes, a Ripper (Arcade Gannon's special version) is in your inventory that is available for use and does not show up in the shop menus, but if it is dropped, you will not be able to pick it up again. [verified]
