DBNO

DBNO (Down But Not Out) is a game mechanic in Tom Clancy's Rainbow Six Siege.

Overview

DBNO is a situation in which an Operator has lost all 100 points of health but hasn't died. When going below 0 health points for the first time in around, players have a 20 HP buffer during which they will enter the DBNO state instead of dying. In this state, the player will slowly bleed to death unless they are revived by a friendly player or hit by a Doc Stim Pistol. If the last shot to hit the player causes enough damage to take them beyond a 20 HP buffer, they will skip the DBNO state and die instantly. However, wearing Rook's armor plates remove this limit and guarantees a DBNO as long as it isn't a headshot.

In this state of incapacitation, the Operator will be unable to stand or defend themselves and have to seek help from teammates before getting damaged again. DBNO players can move by slowly crawling along the floor or they can remain stationary and hold their interaction button to slow down the bleed out instead. The bleed time is the same for all armor values but doubled when wearing Rook's armor.

Headshots will almost always lead to immediate death unless they're shot by Caveira's "Luison" or hit through multiple walls with a weapon with low enough damage.

Excluding special circumstances, each player can only enter the DBNO state once per round. If a player was injured and revived, the next time he/she goes below 0 health points will lead to instant death.

Under most circumstances, if the last player on a team is downed, they will die instantly, granting their enemies the win. Exceptions to this are Doc, who can revive himself, or when one is downed in objective during the Secure Area game mode.

If a DBNO player is manually revived, they will regain 50 HP. If revived by a Stim Shot, their HP goes up to 75.

Frost's Welcome Mats puts victims into an immediate DBNO state if they step on them. While trapped by a Welcome Mat, the victim can neither move nor slow down their bleeding.

The Welcome Mat and Caveira's Luison ignores the one DBNO limit - players can only get downed by their attacks, even if they were already downed before (though this does not mean that they can't kill DBNO players). However, players revived from them are still functionally identical to other revived DBNO players and will die if they suffer other forms of incapacitating damage.

Hostage

The hostage has a slightly higher DBNO buffer than an Operator's and can go into a DBNO state. Though, it will take longer for the hostage to die since it's a stationary objective. This means it is possible to make the game go into overtime if the hostage is still in DBNO and hasn't died yet.

However, the DBNO state is skipped if a frag grenade or a headshot is achieved.

Tips

• If in a DBNO state, do not move at all as this will the bleed out effect to tick down at its normal pace.

• Only move to avoid an enemy's line of sight or to get closer to a teammate.

• Remember that DBNO players cannot fend for themselves, meaning they will die if an enemy finds and shoots them.
• It is still possible to place waypoints when DBNO, so take advantage of that to mark where the enemy may be.
• One way to abuse the DBNO system is to use the health gained from reviving as a regeneration tactic, known as "resetting" within the community. If a teammate is at low health but had not been downed yet this round, their teammates can bring them up to 50 health by downing them first with scratch damage (generally pistol shots to the feet) before reviving them.

• The extra health gained may give them a chance to survive another encounter which they might not have survived if they remained at low health, and their DBNO status likely wouldn't have helped anyways.
