After you complete Mothership Zeta and return to the Wasteland, you will find the blaster in the exact place where it was before.
If you fast travel to The site and keep walk past all the crap left over and you should see a dead alien with a Blaster and ammo
you go to the alien blaster location and jump on the alien space ship
No, however to get more Alien weapons you may purchase the 'Mothership Zeta' DLC.
no
Mothership zeta is not on earth it is orbiting space the only way to get there is by going to the alien crash site and being abducted
theres obvioulsy some at the crashsite where you can find it but if you need more there is some at fort independance [outcast controlled] and theres also some in the dlcs broken steel and mothership zeta available on PC,xbox,ps3
It's already out. Just youtube "Mothership Zeta trailer".
You go to the crashed alien craft which i recommend you go to No Mutants Allowed maps to find and you will be abducted .
On the mother ship zeta expansion pack, if you don't have that you can't get them, besides one alien blaster with limited ammo at a UFO crash site
The normal alien blaster is at the site of the alien space craft. There is a grid of power lines west of minefield. follow them north until you get the alien radio signal, i forget what it is called. Then go off to the right a little bit and you'll find the space craft and the alien blaster, along with about 110 ammo for it. The fire lance alien blaster will be found at a random location selected by the game. I was lucky enough to get mine at the super duper mart. The radio signal is called Recon Craft Thefta Or, North of Minefield
you find it northeast of mdlp power station
once you have completed mothership zeta,everything but Engineering Core, The Bridge, Steamworks, Holding Cells are inaccessable, and the MPLX Novasurge cant be obtained UNLESS you hex/hack it
Mothership Zeta is not coming out on CD, however, it will be packaged with the Fallout 3 GOTY edition which comes out in the fall of 2009. The GOTY edition will include Fallout 3 and all DLC in one package.
