Yes. When you rank up (lt. commander, commander, etc.) and depending on whether you go with an escort, cruiser, or science, you'll get more weapon slots. I believe you get 3 forward weapon slots with the first escort ship (tier 2). I'm pure science, but bought a tier 2 escort ship to just play with in fleet action during open beta, and I'm almost positive it had 3 fore, 1 aft weapon slots.
There are Anti-proton beams as well as Chroniton and Tricobalt torpedoes/mines listed on your list as well as being high-level upgrades in the games skill tree - Does anyone know where these are obtained? I've seen MK 4 or 6 Chroniton Mine launchers, but nothing in the torpedo category. Also the highest level torpedo launchers obtainable at the PvP and exploration traders are Mk X Quantum and Mk X Transphasic.
Would these things be end-game rewards only? Or perhaps have they yet to be added? Either way it would seem a waste of skill points to upgrade their damage at the Admiral level since they would be so rare.
What energy weapons do best against shields or hulls? Everyone says Phasers are good against shields, and personal experience has shown Disruptors best against hulls, but what about the other energy weapon types? I didn't see anything like that mentioned.
Why would anyone use a plasma torpedo though? The defender can target them and blow them out of the sky they are so slow.
because there are ways to slip them in, like breaking shields at point blank, popping evasive and doing a quick 180 (firing the torp from the aft then) and then GTFO. I've done it, and killed people with it before
