The KEW-9, or Keats Energy Weapon - Mark IX, is one of the two versions of the Keats Energy Weapon still in use by the U.S. Military by 2039.
The KEW-8 finally introduced the reloadable/rechargable design that all of Keats's energy weapons lacked, however, it was a huge failure. In response to this, Richard Keats quickly made the next version.
It rapidly fires energy pulses, and has 100 shots before the battery must be recharged or replaced, and usually comes with two spare batteries attached to the side. It loses effectiveness against zombies at round 21, and is one of the best weapons available in Lockdown.
- It is classified as one of the best Nazi Zombies weapons.
