I remember this map being used as one of the main stages in last year's DeFrag Cup and the contestants loved this map. I think it was voted 5 times in a row due to the amount of difficulty and at some point teamwork for several obsticles. In the end I failed and came Runner-Up but this map was the highlight of the cup. It was unbelievably fun and is a decent DeFrag map :).

With this map, it seems you need at least two people to get past certain obstacles. So it is a cooperative-type obstacle coarse.

Cool - I just found this video of this map being beaten... I thought I'de post it here. Interestingly its a slightly different version of the map.

Is this map like the kind where you go though a journey, battle some foes which are actually well put scenery, solve puzzles and then come down to a final boss enemy to finish and win?

I've beaten it

has anyone actually beaten this level?

Very Cool
