Inspired by Dwarf Fortress, I thought levers could be a cool and useful addition to bases and larger vehicles.
A lever is linked to one or more functions or objects in your creation, and can be placed any distance away from them. It can be pulled as a Quick Action, which will activate or deactivate the linked things.
-Opening/closing or locking/unlocking a door or gate
-Setting off explosives
-Firing a weapon
-Releasing the hounds
-Causing the whole creation to selfdestroy
Optional Rule: Timers
Levers can have a timer, which means that when the lever is pulled, a set number of turns must pass before the result happens. This is especially appropriate for selfdestruction levers.
Optional Rule: Secret levers
If you make every lever a different color and write their functions on secret notes that are only shown when the lever is pulled, much fun will be had when enemy troops get into your lever room and start pulling all the levers.
Remus: Harry... I'm a werewolf.
Harry: Are you fucking serious?
Remus: Well yes, but I don't see how that applies here.
