Energy weapons (e.g., lasers) and modern melee weapons (e.g., vibro-swords) use PPS; we get PPS from power packs. Do these weapons need to be connected to a powerpack via a cable, or do they hold a certain amount of PPS before needing to be "reloaded"?
Further, let's say that one has a laser that does 1PPS (i.e., 1 turn = 1 shot), but this person uses his two simple actions to make two ranged attacks - both with his laser- in his one turn. Did this person use up 2 power points or 1 power point?
