Been having occasional LAN games with this map pack since version 1.1, and they have been great, especially King of the Hill on One Hit Wonder. I really like the changed stock maps the most.
The recent addition to You're Gonna Die Big Time is a rather nice one.
The reviews by wrkncacnter and treellama are quite hilarious, considering at least one didn't even download it. I can see they never changed much or grew up. Ignore their false statements!
