What exactly was changed with those subs? There are quite alot minor changes, but mainly it is item layout and quantity, electric grid rework, lighting fixes and additions. Imporant note is that all "hidder items" for traitor gameplay were removed, so those subs are for teamwork mode without traitors.
Small fixes for all subs, aded anti-flooding system airlocks on all subs locking inner airlock door if outer one is open (most advanced one at aegir, but it comes with cost of being unable to intentionally flood sub though airlock).

Still most challenging one.
Has added front lights among other things.
Fastest one by far.

This is a reworked and rebalanced sub originally made by Staticwolf from this topic https://undertowgames.com/forum/viewtopic.php?f=22&p=116745#p116745
It is not a fully tested one so beware, but generally should be working.
One important note - this submarine electric grid system is quite vulnerable to short circuits and fires cause static load is very low comparing to dynamic one, so try to drive carefully to avoid power surges.

I would also want to note that i've marked thread as [WIP] cause we only played quite some games with pre-latest versions of those subs and since I change it continously there might be some small bugs, but technically they're mostly tried and working.
I will update thread if new versions with some tweaks will arrive later on (im pretty sure they will).
