Well, it's good to hear that there are future expansion plans already in the works. Meanwhile that "Scenario" system slots pretty much is just for 1 map. Bit of a waste really so why don't we put it to work?
This will be a limited defensive system that only works against torpedo. Mines cannot be countered by this system.
When enemy fires a torpedo at you, you may deploy Countermeasures if your system is charged and available (standard engineering system checks apply)
but there are two levels of the Countermeasure system
At 4+ charge, you can negate an Indirect Enemy Torpedo hit.
Captain says "Deploy Countermeasures! Detonation Avoided!", Captain may also use this as a bluff even when the sub is not in the detonation area. Say the same thing.
At full charge (6) you can reduce a Direct Enemy Torpedo hit damage by 1. Captain says "Deploy Full Countermeasures! Partial damage taken!"
Either level you use, all the charges are clears after use.
This is an awesome game, hoping for more in the future!
