KOS Online aka Sting Online in Korea, is beginning their beta phase. KOS Online is a MMOFPS (mmo first person shooter) published by DontBlynk in the US and is developed by YNK Interactive.

I have been eyeing this MMOFPS for months as the graphics are looking good and scales well on game systems due to the alleged Source engine with Havok Physics underneath it, the deep customization of your character and weapons. I checked out Combat Arms, a similar Source engine powered MMOFPS, from Nexon in a previous post.
