Watch out for stairs, attacking upstairs is easier than downstairs. You see, when you're about a few steps on the stairs, and a teammate is on the foot of them you can shoot over his head on enemies on top of them and not shoot your teammate in the back by doing so.
In a reverse situation, a teammate on the stairs is obscuring your line of fire until he is at least level with the enemy.
