Ok so i played around with it a bit i can already give you some input:
Both Chems and guns are completely unlocked, that can work for a group of friends but in no way will it work for MP.
The Discharge zones maybe should have a lighting that activates on players coming near it, the should be done to engines.
You provide power control both as togglable switches AND a power distributor? that feels redundant.
Some of the text is a bit hard to read especially with how dark the sub is.

Interesting Shape...
