The short of it is: Anti-Matter is missing, nobody knows why.
"You don't lose levels. You don't have equipment to wear out, repair, or lose, or that anyone can steal from you. About the only thing lighter than debt they could do is have an NPC walk by, point and laugh before you can go to the hospital or base." -Memphis_Bill
We will honor the past, and fight to the last, it will be a good way to die...
I guess I didn't pay enough attention while unlocking things, but now going to make missions I don't seem to see Anti-Matter's portion of the Preatorian's anywhere on the enemies list. Is this do to the fact that unlike the rest of them he should technically only be level 40-45?
