Reviving has not been added to the game
In multiplayer you revive quicker and slightly reload faster
It depends on which mode you are on. On Singleplayer you can't respawn again (which you lose.) But on Multiplayer you can respawn even if your the lowest rank. When you hit rank 27 you can respawn FASTER. So the answer is you can revive in Multiplayer but not singleplayer. BTW: If everyone dies in Multiplayer at the same time then you lose.
