Team Fortress 2 and Left 4 Dead.
TF2's has a spawn room that enemies cannot enter, while this would normally mean that enemies can just sit outside them you usually have either more than one of they have multiple exits. Not only that but they are full of ammo and health, plus you can change class while inside them without a penalty so switching to a Soldier, Pyro or Demo-man will solve the problem of spawn campers.
L4D you choose when to spawn as an Infected so you won't get stuck in someone's line of fire and get shredded immediately. It also allows clever placement to set up ambushes.
