Add me on Steam, I'm from Singapore too. AtheistMentor is my Steam ID.
There's 1 S'porean clan, SG matrix I think. They're pretty damn crazy though, all of them are Club 6 players, and I'm not sure if they're recruiting.
I've recently "graduated" from moving out of Hard games, am able to kinda-hold my own in Suicidal, and on some maps do pretty well. But I tend to panic if I'm the only SS on wave 10, and sometimes I choke inexplicably (missing straightforward FP decaps).
