Other
-When you unlock Super Veritech Mode you can press "X" to
double the stats.  Not to mention a new look.  (Can only be
used in space).
-When facing carriers, constantly roll to avoid their laser batteries.
-Multiple targeting works best to destroy the laser batteries on a
carrier.
-You should always use boost.  Your faster, harder to hit, and
ready to perform maneuvers.
-Press "Y" in Guardian Mode to pick up objects, and
people...
-Don't over use your weapons.  They still need time to recharge,
plus you will need them if something arises so it's recommended you
save at least 3 missile pods and keep your gun above halfway.
-In conjunction with previous tip, don't be trigger happy :).
