I found this amazing opstical course on sandbox that was REALLY challenging! I put it in my file share so go to it and download the game and gametype. The map is "TheGreatEscape" and the gametype is "canYOUescape?". Time yourself and if you beat it in under 8 minutes and you have video proof I will give you 1600 MSP! Even if u beat it not under 8 minutes, still reply that you did cause I think it's crazy hard!
