X-7a "Left Field" Artillery Launch

The X-7a "Left Field" artillery launch is a location in the southwest of Big MT

Layout
The outside of the area is guarded by an RY-589 Ultimo bot, which drops a LAER upon its death. A Y-17 trauma override harness team with several lobotomites stands just outside the hole in the northeast fence. They remain grouped together until attacked, making a good target for grenades or the missile launcher found in the truck due west of them.

There is a military truck that has crashed through the artillery command center's wall. This truck can also be seen from inside of the building. Outside of the command center is the artillery launch gun control console, which fires the fixed artillery at the X-7b "Boom Town" target zone.

The indoor area of the command center has a couple of skeletons, some proton throwing axes, and an explosives skill book workbench recipe. The holodisk is located on the small edge of the soundboard in front of the artillery shell when first entering the room.

Loot

 * RY-589 Ultimo bot - Can be found carrying a LAER
 * Recipes - Explosives skill book holotape - Inside the artillery command center, on the big machine that is above three ammunition boxes.
 * Missile launcher - On a truck outside.
