Beforehand, yes, yes, I know, you all hate COD. I don't care. These videos just paint MW3 in a negative light anyway. The spawns are seriously just horrible. To the game, as long as the place you're spawning has no one in sight in that instant, it will spawn you there, regardless of proximity to another player. Also, regardless of how far away from your team you actually are.
First one is self explanatory.
For the second one, the first clip just shows the bad spawn. The second one shows me killing the exact same guy 3 times in a row. The last kill was cut off, which was a throwing knife to his head, right when he spawned.
Third one, you might want to watch the killfeed. Guy shoots explosive barrel while trying to kill me, I kill him. Spawns a short distance away, kills me. I spawn a few feet from where I died, kill him from my spawn. Run into building, the explosive barrel he shot accidentally killed me and another player.
