any other way? i just need to beat the ICS, my omnidirectional TeV blaster is not powerful enough for it's shields

there's no such menu

can u pls tell me how to use the GOD mode in the game.. i need to defeat the icorym command ship

this might sound foolish, but i've downloaded the GOD mod and cheat mod and have no idea how to use them in the game (my omnidirectional tev9 blaster has no effect on the icorym command ship's shields).. pls help!!
