Laser cannon

The laser cannon is a weapon that was to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.

Characteristics
Constructed by Trig using the laser pistol schematics to create a giant version, the laser cannon is the sole thing keeping the Vipers from attacking the Ciphers. What the Vipers don't know is that the cannon does not work. The Prisoner can help Trig fix the cannon, and get a CGI cutscene of a group of Vipers being roasted as a reward before the cannon explodes.
