Halo: Reach Cheats :
Secret - Weapon effectivness
Covenant weapons are more effective in taking down shields. while Human weapons are more effective in depleting health.
It is wise to use a combination of a Covenant weapon(Plasma Bullets) and a Human weapon(normal tiny bullets).
Example: Plasma repeater + assault rifle. Use the plasma repeater to kill your foe's shield, then take out the assault rifle to finish him quickely...
or take out his shield with the plasma thing and then smack him with R1 at close range.
