Ke0's Gaming Arena or KGA for short first appeared as a Server, established by ke0, for people who uses illegal (non-steam) counter strike source. Since then popularity has sky rocketed since there are only a few servers that does this with a reasonable ping. For some reason, ke0 and the community has disbanded and never heard of again until Ech0 rebuilt and rehosted everything from where ke0 left it. The most interesting server and mostly played and widely popular is the Zombiemod Server. Check out KGA and join the community. :)
