Especially when exiting the temple in the first part of the game, as you come across enemies, find a good place to hide. If a partner is at hand and is standing next to you, they should start shooting the enemies. All you have to do is hide and your partner will shoot everyone down and kill them. Your partner won't get shot because that is how the game is programmed, you won't get shot since you will be taking cover, and the enemy will be annihilated!
