Underwater bases in Unturned 4.0 could be harder to raid, than in Unturned 3.0.
I would suggest deeper oceans(if there are any) and water that is hard to see trough(It’s a zombie apocalypse, you can’t have clear water), so when you try to make an underwater base you will need scuba diving equipment.
Also for the underwater bases. They can’t be made out of wood, since it would leak. That will make another use of materials like metal and whatever else Nelson adds into the game.
In addition, water bases in 3.0 require an oxygenerator, which is very unrealistic. A solution for that is, if a water pump is added, so when you make a base under the water you can pump it out.
An airlock will be easy to make.
●15:37 - What will happen to sky bases, underwater bases and free form building like placing
I also don’t see zombies coming to raid you while they swimming or just submerged walking underwater maybe like 2.0 style water base building but no underwater bases
My Personally opinion
Do not think that that would be so good as ,I think that unturned 2 will put a bit more on realism and underwater bases are a bit stupid at all because of the raiding and that it would be relatively unrealistic
(Sorry for my bad english, i hope you unterstand it)
I’m fine with no underwater bases for II, but if they do show up then I hope they are built in a somewhat similar fashion to Subnautica bases, requiring hatches, reinforcements, special underwater compartments, etc with proper flooding mechanics. Still like Nelson said in the interview, having to “subtract” water isn’t something he has as top priority.
