Red Zone

The **Red Zone** is a gameplay component within surviv.io. Every round, the Red Zone narrows down the gameplay area more and more as time goes on. Should a player be stuck in this zone, their health will deteriorate slowly. The red zone increases in damage and decreases in time between movements as the game progresses.

## Mechanics

When the game begins, a white circle is shown on the map as the "safe zone". As time goes on, the Red Zone will move towards the white circle, and stop just at the outer perimeter of it. The area outside the circle will be entirely imbued in red, and you will take damage upon entry. When the Red Zone reaches the outer perimeter of the safe zone, the circle will automatically shrink, and it will be another few minutes before the red zone once again moves towards the smaller circle's outer perimeter. The smaller the safe zone is, the more damage you will take going out of it. If the players are in a stalemate near the end, the Red Zone will engulf the entire map, inevitably leading to one of the players dying.

It *is* possible to see the red zone outside of the map at the very beginning of the game if one heads to the very corner of the map and has a high scope. If you die from the red zone, the kill counter will read “Player died outside the safe zone” or "Player finally bled out", in the case of downed players. The red zone will not always enclose in onto the middle of the map; sometimes it will be towards the edges or somewhere in between, so never depend on the fact that you are in the center of the map means you are safe from the red zone; it spawns randomly and it will depend on the game for where the red zone encloses.

If there is only one player in the game (as often happens on Twitch servers), Red Zone countdown will not start until second player joins the game. Red Zone closes in eight steps:

Note that Total DMG is if you were in the red zone the entire duration of that zone, even before the red zone was on the accessible part of the map.

Also note that the damage values have no real confirmation, and are just a general area around which the damage is.

## Tips

* If the players are in a stalemate near the enemy, the safe zone will shrink entirely, forcing the players' health to lose until all but one dies. You can heighten your odds at winning by using a Med Kit right as the red zone starts dealing damage to you as well as ensuring you have the maximum level of Adrenaline.
* If there is good loot in the red zone, and you have many Healing Items, then it could be worth a run back to retrieve the loot. Try to use Sodas or Pills. If it is at the end-game, then don't run back, as the Red Zone deals more damage at the end of a game.
* Run with no Weapon equipped when running from the red zone, as you will be much quicker, though if an enemy is also attacking you within the red zone, you may need a weapon to fight back, slowing your progress out of the red zone.
* Using adrenaline negates the damage dealt by the red zone, losing and regaining health.
* One doesn't necessarily need to get out as soon as they find themselves in the red zone. Sometimes it is better to stay on the edge of the red zone for a short amount of time to make sure there are no enemies waiting just outside.
* If you can, force your enemies into the red zone! It will cause them to either use adrenaline or slowly lose health, and the battle might be in your favor. However if you are seeking a kill, be careful and make sure you land the final blow. This is best done late game. Throw grenades all around, which will either kill them, force them into the Red Zone, where you can easily gun them down, or come very close to you where you can melee them. Obviously, make sure to leave yourself some space so you don't blow yourself up (unless you have the Flak Jacket perk, in which case you can be more aggressive).

## Trivia

* The red zone's exact color is `rgba(255, 0, 0, 0.6)`, which can be alternatively written as `#FF000099` or `#FF0000` with 60% opacity (40% transparent).
* Theoretically, it is possible to survive more than 8 minutes, provided you had enough Consumables, healing meds and Adrenaline, and if there is another player still left surviving.
	+ You could survive up to 28 seconds on Med Kits, but only up to 5 seconds by using bandages with no Adrenaline.
* In the code, it is referred to as "gas". This might give some insight into the lore, suggesting that PARMA developed chemical weapons on the island.
* Most Battle Royale games have something similar to a red zone that shrinks in time and deals damage.
