I've been following this mod since the very beginning, it is incredibly sad yet understandable to see this mod close. Since the start however, all I ever wanted was to rock around as one of these awesome Chaos warriors in single player. Such a shame that you guys couldn't just consolidate all your current work into a single player re-skin, the models alone would make the single player ten times more enjoyable.
Personally I think it was a wrong move to focus on multiplayer first. While everyone loves a bit of PvP, eventually regular players move on and the server population dies down until eventually no one plays anymore. However with a singleplayer focus, you can keep coming back to it years after it's released and still get the same level of enjoyment out of it, plus you can still recommend it to people while the multiplayer is being worked on. Just a little food for thought for any future projects.
