For player use, it can be a fast missile ship with two Potato M1 satellites and a Small Tachyon Beam in addition, or four Small Lightning Cannon M3s.
The Spike MK2 uses different types of L weapons, and isn't too much of a threat unless at close range;
Non-veterans use a Laser Cannon, and are easily dealt with from long range.
Veterans are equipped with a TU-assisted Fusion Beam, and are incredibly faster than non-veterans.
Double-veterans are equipped with a Small Tachyon Beam, and are very fast. At higher levels (especially in gauntlets) they pack huge damage and can cause chaos for the unprepared; therefore the player should prioritise destroying them.
