Could go on about all the same things everyone else will, the four shots, no scopes with the sniper to the face etc., but I want to post about the incredible griefing potential the game had.
My brother and I once, over split-screen, were in a ranked CTF match. Level is Valhalla. Two teams of four. In our (blue) team, there was also another couple of guys on split-screen. Let us call them Arbiter and Arbiter [1]. Right at the start of the game, we start betraying Arbiter. Obviously annoyed, he betrays back. Now, we are careful not to betray a second time as it would give him the option to boot us. Instead, we shoot at our team mate and pretend we are trying to kill him again. So, Arbiter betrays us again. I get the option to boot him.
But I wait.
My brother plays on, and all that was previously mentioned took place about only a minute in to the 15 minute match. There is still about 14 minutes to go. So my brother, and the two other guys in my team play on. Eventually, after much battling and hardship, there is 30 seconds left, and the score is 2-1 to us. It is pretty obvious we are going to win. Arbiter and Arbiter [1] are walking back to our base with the red team's flag, and if they land it then we win 3-1. They are walking up the metal base, and there is only a few seconds left. Arbiter is JUST about the land the flag on the podium, but suddenly...
I press the boot button. Arbiter and Arbiter [1] are disconnected from the game. The game ends. Me and my brother win the match and gain EXP. Arbiter looses EXP for being booted from the game, maybe goes down a rank, and has had 15 minutes of his time completely wasted. Me and my brother were crying with laughter.
