I know I'm going to get flamed for this but I really enjoyed playing this game.
The Exp is pretty much the same, so if you hated the duke you aren't going to like this any better.
WELL worth the $2.50 if you ask me though.
Duke Nukem Forever: Hail to the Icons Parody Pack is also only $3.24.
Not a good buy unless you are really into your duke multiplayer.
Bought DNF off Amazon for $1USD (Steam-activated) earlier this month. I don't think it deserves a cent more tbh.
