In the way of new grenades, durign the E3'03 demo, one of the marines yelled, "Frag and clear!" He threw a grenade at a groupd of covenant, and after it exploded, the Master CHief went in to finish them off. However, it looked liek the convenat were stunned, blinded. He said 'Frag' but it looked like a concussion grenade. CHeck that out and correct me if im wrong. Yeah, I was the one who posted about the Rocket aluncher locking on only when zoomed in and in range, so I dont THINK that it could track halfway across BLood Gulch, im not worried abotu that, But i hope that the rockets, or missiles, wahtever you want to call them, are destroyable. Of course if they're not, no big deal, but if they were it could be cool.
