What you do is you open Game Editor, then you pick 
the format of the game that you want eg.(1 player, 
2 player com, 2 player coop) and you boost the ships 
guns and shields up to 999, or the max. . 
Also, you should put Fricton on 0 (you go faster), 
shield repulsor and destructo, and make the weapon 
types the best eg.(killer ammo, heavy ammo, and 
instant death ammo etc.)
