Call of Duty: Modern Warfare 2 Cheats :
Easter Egg - Explosive Rounds
Explosive rounds can be used on the MG4 (confirmed), and the L86 SLW (not confirmed), simply by adding the 'FMJ' attachment onto it. FMJ is unlocked after 300 kills with a weapon.
The weapons name will change to ' --- Explosive rounds' and will say this in the pickup icon, killcam and to any spectator.
