Laser cannon

The death cannon was a weapon in Van Buren.

Background
Constructed from ancient pre-War plans left by the original inhabitants of the Mesa Verde area, the death cannon is the sole thing keeping the Vipers from attacking the Mesa. What the Vipers don't know is that the cannon does not work; the energy capacitors are burned out. The Prisoner could help Trig fix the cannon, and get a cool CGI cutscene of a group of Vipers being roasted as a reward.

Appearances
The death cannon only appears in Van Buren.
