My favorite weapon to use when I cannot seem to kill something quickly enough is my Alien Blaster. I randomly found it when I killed a couple Aliens up North around some rocks. It doesn't have tons of ammo with it, and I cannot seem to find more! I have read other places that there is more, and then I have read that there isn't any to be found. Where can I get more if I can? Thanks!

You only get what you loot off the Alien, sorry.

You cant. (unless you are on pc and you can use console commands)

You can use a glitch to get more ammo.

Take the blaster and one power cell.
Go to a fiends area.
Kill ONE fiend.
Place the blaster with one piece of ammo on his/her body.
Let another fiend pick it up.
Let this fiend equip it.
Enter VATS, kill him/her.
Pick it up.
You should now have around 4 to 12 power cells on you.
Place the blaster and ONE piece of ammo on the fiend body again.
And repeat.

This worked in FO3, don't know if it works in New Vegas.

As Colonel stated, there is only what we loot when the weapon is gained and no more.

That is so sad! Thanks, it does save me tons of time!

I think fishy's method will work. I think ammo still works the same way it did in F3. The gun will have a few cells in it to use.

Still it's a beast of a weapon for a hand gun and there is also Pew-Pew.

It doesn't make much sense for people to be selling them or you finding ammo for it left and right, since it's a Wild Wasteland thing and more of an easter egg.
Doesn't it also have crazy criticals? I think the low ammo count also serves to make it not so overpowered and let you think when to use it.

Agreed! I use it only when I am really, really in a bad situation and it always gets me out. Like the time Blind Deathclaws were EVERYWHERE and I didn't have my buddy, Rex. I have about 15 shots left. I refuse to use them on anything almost. I just run back to the Brotherhood of Steel if I get way too overwhelmed as soon as I am hidden again. haha, safety for a minute makes me feel better. I can get worked up!

Legate Lanius doesn't look so tough when he turns blue and disintegrates into a pile of ash.
