Mounted A7 laser rifle doesnt take any time firing I simply hold F and shoot as many rounds I wish without even a second passing.
Which version of the game are you using?
Sadly I don’t know how to convert that to a version I know. did you use 0.C or one of the experimentals?
downloaded ASCII experimental on 17.7.2016
was testing this a bit more and oddly time does seem to move forward, eventually, is a bit strange thou, havent been able to count how many shots i fire before time moves forward but it must be over 300… holding down F for 2 min at least with around 3 shots per second fired before it moves forward.
Same with mounted fusion gun:
