Get some badges and buy an uber turret for gods sakes, or do like me and kill anyone with enough balls to attack you.
If you can't handle the space combat system, i reccomend getting some skill, cuz i deal with grox attacks with the pulser lazer, which is incredibly hard to aim=P i reccomend moving and turning while luanching proton missles if your ufo is crap tho
