how about a map where you have to play on an oil rig in sea
something like this:
the specop's gear should be a diving suit, because the specops sepose to have swam to the oil rig with diving suits,
kinda like this:
cant get any better examples, but sometimes the navy seals or any other special forces have their diving suits on in the middle of their mission, so devs could maybe design a diving gear for specop for particular maps like "oil rigs" to give that realistic feel,
