Here is the list of bugs I experienced:
- An horrible sound instead of the normal sound for jetpack.
- The game doesn't seems to have any frame limiter, it goes to fast on the tutorial.
- The mission in the zombie cave doesn't have the script that make Ronin come in ambush.
- On Dummy assault, the game lags and become unplayable for no apparent reason after you reach a few meters to the left of the first door
- I thinks there is a bug too with magino defense, but I can't remember it.
- Mods don't work.
So, the only playable way of playing CC on Linux for me is playing the tutorial over and over, and without sound. It's fun and tedious at the same time.
