Compartment Door Open/Close Sounds

The stock sounds are awful.

The best two overall sound mods I've encountered are CaptHelm's and Stormy's, use your preference of the two. I go with Stormy's because I like the extra murmured background voices and general sounds of life on board.

As for the compartment hatches, I honestly can't remember if either of the packs have had a sound for that. Would be a nice idea, but somewhat of an immersion killer to have it go through the whole 'spinning and tightening' routine, since that would take several seconds, and by that time your character is halfway across the next compartment.

Water sloshing in certain flooded compartments when you walked through would be an interesting touch, but would be odd to see since there is no visual water that accumulates. In general, a lot of the damage sounds are IMO difficult to mod just because the stock visual representation of damage is so underwhelming.
