Aw gawd... now I have to invent some garbage to make a story line
Sheesh, just like Hollywood.

Hum de dum <thinking music>

Ahh, this will be perfect.

Okokok,

There has been some major dimansional stuffup on the other side of Phobos
(in the super secret military base).
Apparently the base seems to be warping, changing into something else.
Marine recon corp has reported a 'castle like structure' superimposing
the base buildings... 
Your platoon is sent to investigate. Being new to your group you are assigned
to covering the rear of the group (typical isn't it) you hear screams and 
gunfire as your expedition is ambushed just after entry into the complex.
You end up separated from your buddies, you are unsure if anyone has survived.
Finding a shotgun by the cold corpse of your platoon leader you seem determined
to find out who is responsible for this. 
You step onto the complex grounds to find that half of it has been morphed
into a giant castle inhabited with evil, vile creatures.
"This map is totally fucked...", you think...
"This place ain't what its spossed to be,  that's fer sure. 
 Well at least I found some shells ... <growl> huh? wtf? 
 <swoosh> <bite> arghghgh!"


Have fun 8)
