Lol, probably nerdy, but was your heart going a good'un towards the end?
Mine still does. I got one the other day with the HAMR, got to 25 and host migration kicks in, as me and an enemy are facing each other. Thought that was it, but managed the kill. Didn't think it was going to come because the enemy were few after the migration. That, and my bleeding K9's kept jumping them. :/
First Nuclear with lethal scorestreaks - I used AGR, VSAT and K9. I still can't get a Nuclear with using the player controlled streaks (Lodestar, VTOL). My helpless body is always found, lol. :(
