So, my friends and I were playing in the Halo: Reach beta. Our team is winning, but the others are making a comeback. One of my friends was cornered by an enemy. He stuck his opposition, and started to run away. The enemy team member chased him and tried to assassinate him, despite being stuck. Another opponent ran up behind his team mate currently trying to assassinate my friend. The Plasma Grenade detonated while the player was on his back and my friend lived and got a double kill. We like to say that this won us the game.
