Monsters still spawn in inaccessible areas, though not as often.
This script is playable on any map. The goal is to live as long as possible. It becomes more difficult with each round due the the increasing number of monsters spawned. I would advise playing this with a friend. When ever your friend dies you can find their body on the overhead map or the radar. Once you arrive at their body, you hit the action key to revive them. Be careful because once everyone dies the game ends.
Don't forget to host as a gametype!
Since version 3, the window error brought up by president is no longer an issue
