I was playing MW2 yesterday on my new favourite game type Search and Destroy, this is probably because I became sick of all the Chopper Gunners spawn trapping our entire team in every other game mode, I once got so sick of it I when to get some water from my water cooler. Since everyone only has one life per round there is basically no chance of anyone getting anything but the lower end killstreaks.
There are more campers in search though; this is probably because of the one life rule and the fact that there will be at least one guy trying to plant the bomb within the first 10 seconds of the game by sprinting at the closest bomb and most probably getting sniped in the face by waiting snipers within the first 5 seconds of the game.
For the most part however Search is actually the only game type where one guy cannot carry the entire team, and also the most fun to watch even if you are dead due to the epicness of watching the last two guys have an epic battle at the end of the round usually accompanied with complaints from the loser about how whatever killed him was nooby, or watching your last guy stuck in a building get owned by five enemies.
I find team tactical Search to be better due to the fact that it’s 4v4, therefore less likely to be infested with campers and quickscopers and if you are the last guy alive you will only be against at most 4 guys rather than 6, and it is usually more fun in general.
Basically Search just cuts out all the multiple rage incidents that are in most other game types, and just concentrates on one huge rage incident when you are sneaking around the map and get shot in the back by a random camper.
