Thanks man!
For what it's worth sound wise, the intro mission gives you an ion peashooter, the worst weapon in the game. It's designed to sound weak and akin to a wet noodle, it is also a powerful disrespect to peashooter someone to death in mp with such a weapon. I guess the problem is, everything in the intro is using peashooters... I'll figure something out.
The sea sickness may be solvable with some of the options, we have a wide 110 default field of view as well as some minute camera sway on by default. Specifically you'll want to adjust the FoV to taste, and then zero the following: Cockpit sway strength, look ahead strength, roll ahead strength. That may resolve it for you, but everyone is different.
