we need more weapons of mass destruction !!
better point defense systems.
specialized hull and engines for better zap and go tactics.
ripping a page out of Master Of Orion 2 : stasis fields gota big ship problem ? no worries just stick em in another dimension until you can deal with it.
weapons with area of effect. for example bomb launchers that unleashes a big Kaboom !!
projectile weapons with various projectiles that do various kinds of destruction.
Projectiles that on impact shatter into hundreds of pieces showering nearby targets with deadly shrapnel.
Projectiles that are designed to deeply penetrate armor and then explode causing deep internal damage.
And last but not least .
to counter all those pesky lasers.
Aerosol Bomb !! tired of all the freaking beams coming in at your ships ? then just disperse them literally, with the handy dandy aerosol bomb. Watch that deadly beam of energy be dispersed into nothing more than a pretty light show . oooh ahhhhh.
what fun is a battle field if its all just a bunch high powered torches any how ???
