What a fun map this was....I really enjoyed this level..just playing it solo! You will need to download this, if for no other reason, just to release some stress. Supports almost all the modes. The ball is clearly labeled. There is a central elevated room that does give you acess to the outdoor pations. Just be patient and keep looking, if you stay alive that long. (My 5 year old son found it, after I had given up!) Only drawback of this level is the teleporter room.
