Er... the weapon description for ALL neutron weapons have the line:-
'neutron weapons are the most energy efficent, but they lack the range of other energy weapons' (thats a rough quote of the top of my head)
The corsairs use neutron and pulse weapons.
Particle weapons (and most of the others too if I remember right...) have:-
'particle weapons use alot of energy'
Plus the BHG's particle cannons has this line too:-
'the -insert weapon name- sacrifaces energy efficency and damage for increased range'
I have noticed that particle weapons use alot more energy then other weapons, apart from plasma ones of course, so it's probably been done on purpose.
And don't forget particle weapons go through graviton shields just like plasma weapons do. So if you can't get pulse weapons (or don't want to use them) mount particle and plasma weapons and you'll still drop a PvP opponents shield fast (and do hideous amounts of hull damage once the shield is down too :laugh: )
