Deutrium? Don't they usually need that for propulsion in the series?) but never mind me do whatever you want I'm just a bit confused in gneral
Firstly, you surely mean the isotope of hydrogen which is called Deuterium and secondly,
the propulsion resource in Star Trek is called Dilithium. I would prefer DIL or DL in the GUI.
To the torpedos: there were only Photonic Torpedos for the Federation in Star Trek Enterprise (the NX-01 series) which makes it fine to use PT there, as long as you don't plan to add Romulan/Klingon/whatever ships there.
Season 3 added Photon Torpedos IIRC but PT is fine there too.
/nerd rage off
I like your Photon torpedo sprite and they're fine IP/lore-wise
But honestly I would prefer a Phaser-Beam weapon to the Phaser cannon as a starting weapon with an orange, continuous beam.
:edit: :nerdrage: Finally, the thread has been updated to LCARS and not ICARS Theme. (One thing that bothers me: The NX-01 didn't have LCARS, it was introduced in Enterprise D, which is more than 200 years later lore-wise.)
