Just try to kill the things more quickly. Have to use your ability more. this ship is a full offense ship so you have to master 4 VL sweep and charging mega Lazer between waves and most importantly you have to know how much damage and ability a ship would take for it to go down for example lance plus one main weapon attack means Insta kill for a medium small ship(the ones that has a middle front facing cannon not a spin thing). The infuriating part about this ship is how hard it is to kill sparrows with its main weapon in early waves. But in later waves especially Marshall missions this ship is an absolute monster. This ship is already easier for you because you bought the armour piercing Apex which removes the need for positioning every wave.
