Man, I've never heard about FoK until just now. I just watched the trailer and it looks seriously awesome. But I'd be afraid to install it and have it overwrite stuff like sounds (possibly screwing up my soundboard efforts), plus my PC is old, depending on how detailed the new textures are, I'm not sure it can take it.
PLUS I'M A NOOB AT MP Especially since the system is revamped!
xD Thats ok, I got totally raped first try, but FoK is based on tabletop. so HEavy bolters wont to sh*t against tanks. Which makes the whole game more like "What should i do?" instead of "A bit of this , a bit of that. HA i won ".
There are even more sounds included and will not overwrite the source data since it is an Mod that has to be loaded into the game. (if you get what i mean) meaning you can load the "Vanilla" version of it all in the blink of an eye . but about your pc, that might be a bit of a problem >.>
