Exo Medic costs 1500 Credits in multiplayer and 500 Credits in solo without needing the player to have the Exoskeleton. When the player is downed, they will be equipped with their handgun (Atlas 45 if the player doesn't have one (Uniquely, the M1 Irons can be used akimbo when down), or CEL-3 Cauterizer if the player is in possession of one) while they are down and will be revived shortly after. The zombies will move away from the player while they are being revived. In solo, it can be bought only three times before becoming unavailable for the rest of the game.
