DBNO

DBNO (short for Down But Not Out) is a game mechanic in surviv, exclusive to squad and duo gamemodes. It is a state in which a player has lost all of their health points but has not died. Instead, they reach a state of being "downed" or "incapacitated". When playing duo/squad games, players will always recieve this stage, as a sort of "second chance" before dying; players will not instantly die when all their health is lost before they are downed. There is one exception however, and that is if there are no standing teammates. If all of the player's teammates are downed, or killed, and the player loses all their health prior to being downed, then they all die, and thus, they lose the game.

Being downed
When knocked down, there are a few things that happen to the player: Players are of course, extremely vulnerable when in this stage.
 * They recieve an additional health bar that slowly decreases, or "bleeds out".
 * Their movement speed is drastically decreased.
 * Their FOV is reduced to the size of a 1x scope.
 * They cannot use any weapons or items, including medical supplies. Players can still drop items.
 * Any existing stamina is lost.

Reviving
A player can revive their teammates by pressing F near them. While reviving, the teammate stops bleeding and the player cannot perform any actions for a few seconds, although they can cancel the revive. Both the reviver and the downed player can still move, but the reviver's movement speed is very slow. This makes both players also very vulnerable.

After a player is revived, they are returned to their normal state, albeit with only a bit of their health, which can of course be healed. The player still has all their gear prior to being knocked down. Any stamina that the player had before being downed is lost.

Strategies

 * If a teammate is extremely low on health (less than the amount that they are left with after reviving), you can deliberately knock them down using an explosive, and then revive them. They will have more health after they are revived. This has some significant risks however. The benefit is small, it leaves you both vulnerable, and not to mention, they'll probably think you're a jerk for doing that. This should only be used as a last resort if neither of you have any medical supplies.
