Also, you cannot drop a grenade once the opponent has started an execution. The grenade will still have a timer when you drop it, so it'll take a little more skill than just simply pressing the right trigger. If you have a Grenade equipped when you're downed, you can press the right trigger (RT) to drop the grenade, and commit martyrdom. Now you can crawl around as a last desperate attempt for life, and rapidly tapping the A button will help you crawl faster.
When downed, you aren't as helpless you were in Gears 1. The game also includes the ability for a player to duel with an AI or human opponent when both use the Chainsaw Bayonet attachment of the Lancer Assault Rifle. It includes a more profound plot with new characters, new weapons, and new enemies, including the ability to fight Brumaks.
Much of the core gameplay elements that were central to Gears of War, an over-the-shoulder third-person shooter that emphasizes the use of cover, are present in the sequel.
