A great add-on to an already great game.
there is new levels in the game but they are not free roam like in postal 2 they're more linear levels and i found most of them a little more frustrating than the last game and i had it on normal difficulty but anyways there are new levels like:
The hospital (Donating sperm for money, and escaping the Gary Coleman hallucinations and Dervish Cats)
The town (Restaurant fight against zombies)
The farm (Infested cow slaughtering)
The rival video game company (Retrieving the Golden Disc)
Vince's house (Defense against 80 zombies)
and more.
and that's mostly all there is too it, this add on comes with the awp modded postal 2 version if you install it correctly as i said in my postal 2 review im not responsible for any bad things that happen to your computer because of your incompetence. more reviews on the way! nickito14
