Face's next map is Tremlantis and there isn't any part where you can't drown and the object is to kill the enemy base before you get ragequit at "missing file GURP" where the sound of a building getting hurt is made in its place.
I also made a map [lost now when hard disk died] where everyone is on a sinking ship and to get to the other's base you have to travel through obsticals and mazes in water without drowning.
With the 'missing file gurp' or whatever the sound file is, i don't get that message and i actually do get a drowning sound.
With water, i don't see any logic on why guns, high speed barbs [adv goon], and especially flame throwers and jetpacks work underwater. [i think flamer was fixed in 1.2 though, not sure].
You can't expect that much from trem.
i make new character called mphelpy and he swim fast like dolphin. alien cannot even catch. he swim to overman and make him boom 
It's not the humans you need to make a character for, it's the aliens. 
Why not make an alien class that is similar to the 3rd angel from evangelion [anime] and as soon as it grabs a human, it explodes [kiling itself + human if human isn't a bsuit] and damages everything in close range?
For those who don't know about it and can't be bothered searching it up, this is what is can do:
Swim [why wouldn't i be mentioning this?]
*Short range (weak) proton beam
*AT Field [a barrier which nothing can get through
*Fact of being a super giant freak
Regeneration over long period of time
Self destruct in emergencies
*These will make aliens unbalanced so these don't count
In other words - it is a completely useless class except doing a kamikaze into humans under water!
