Crashed Anomaly

The Crash Site is what appears to be the remains of an alien craft that has crashed inside of a house across the bridge near Greener Pastures Disposal Site. As you enter the crash site, you will pick up a strange alien signal on your radio,the area is also lightly irradiated which indicates you are getting close. The crash site is surrounded by 2-3 radscorpions. Once you find the crash site, you will see the corpse of an alien, along with his weapon (laying by his right hand). The alien blaster is a one-handed pistol with limited ammo and is unlike anything else found in the game. The alien blaster is capable of one-shot kills and is incredibly useful.

In addition to the ammo at the crash site there are roughly 80 rounds in the outcast base Fort Independence, as well as on the top of Anchorage Memorial, beneath a military truck east of Fort Bannister and outside of Vault 106.

Ammo can also randomly fall from the sky as a part of a random event.
