Insurgency MOD: PC Gamer Exclusive!

[Jeremy]

What I find wierd is that the game seems so close to CS.

I'd suggest reading more about the mod:
http://www.insurgencymod.net/tour.php

or read PC GAMER's preview:
www.pcgamer.com

It would be hard to know what the mod's about and then possibly compare it to CS so you have some reading to do
