>.> This was found when modders were playing with gametype options. So it was considered and left in the games code. It's amazing what modders can find. In case you don't get it: There's a perk/deathstreak in CoD 4 and MW2 called Martyrdom. Every time you died a grenade would fall from your body and go off. Modders found a similar feature in the coding of Halo 4.
