Map - ze_antartika (b2)
Where - http://css.gamebanana.com/maps/178382
Why - I'ts very enjoyable but pretty hard and requires teamwork.

Here are some videos for each stage:
Stage 1 :https://www.youtube.com/watch?v=eJt4...2B9jts&index=1
Stage 2 :https://www.youtube.com/watch?v=nTBh...2B9jts&index=2
Stage 3 :https://www.youtube.com/watch?v=kCc7...2B9jts&index=3

P.S. :I didn't make this videos
P.S.2 :I know these videos feature the b1 version but there weren't major changes
