I think the game is great! It contains:
-Edgy humor (of course)
-It's own Steam Workshop Community.
-Lots of free activity during your objectives.
-The ability to urinate.
-Good weapon variety.
(Go to the Steam Workshop and you'll eventually have a huge Arsenal)
-Three Difficulty modes not enough? Why not alot?!
-Plenty to explore and discover secrets.
-Cats used as Silencers
-a fun extra DLC if you're interested and isn't forced upon you.
-Mocks the majority of Stereotypes that even the actual stereotypical person who's playing laughs from it.
-No story line is even needed to understand this game.
It's worth buying even when there isn't a steam sale.
