Good, but a lot of the techniques used have been deprecated (Or is it depreciated?) or... in other words... are now obsolete, the guides are pretty much incomplete based on research I've done, and are otherwise unclear on these things...
ADDENDUM: So COH runs on the SEGS engine and is actually OPEN-SOURCE! How convenient, though I'd imagine that the skills required is pretty high up there...
ADDENDUM 2: Looking further into it, I don't see how the engine is even usable, being as the 7z file and the folder, even the "client" is missing executables, could be SEGS, could be something totally proprietary, I don't know anymore
