Fireworks
Don't plasma grenades look great when they go off? Especially on an Elite's head...
All you need for this cheat are 2 Plasma grenades.
This is possibly the easiest thing you can do in the whole game!!!
Simply throw a Plasma Grenade (only a few meters away so you can still see it.)
Then WITHOUT MOVING THE AIMER throw the next one as soon as you can. It should land on top of the first one. When the first one explodes, the second should be shot striahgt up into the airt, where it will explode at the very peak of it's jump! W0W!!!
