This is my first mod. It's a small armory/shooting range near Vault 101.
Steps:
Start at Vault 101 door.
Go down hill
Turn left
Follow road
turn left
enter door to Lost Armory.
Includes: Many guns, every type of ammo maxed out, shooting range with milk bottles for targets.
IMPORTANT NOTES: I screwed up when editing the Wasteland, so you find that some rocks are out of place. Turning off the mod may fix this.
