Perks

are special Items/effects that are sometimes given to Players in surviv.io. These perks vary depending on the rank that the Player has. Perks can be found most likely around the map. Each perk stands a different purpose of use. There are many different perks in different modes.

Using

 * Mass Medicate
 * Keep close to the teammates. When they need to heal, just click one of the consumables (full for you), and call the teammates to heal both them and yourself. It is also useful when attacking one of the Bridges in 50v50, as the medic can heal many players faster than adrenaline with just Bandages.
 * Endless Ammo
 * Use the Perk's advantage to fight with opponents with guns that require special Ammo without running out of Ammo.
 * Keep reload your guns when not fighting to not waste time dodging the bullets while reloading.
 * If you are skillful enough, you can find a Flare Gun, spam Air Drops to bait players, and kill them.
 * This perk is less effective in Potato mode, as rare ammo tends to be more common, and the guns that shoot them are swapped upon a successful kill
 * Splinter Rounds
 * In addition to the considerable intimidation this perk creates, it increases overall damage of all guns to be 14% greater if all bullets hit. This effect is devastating when using high-damage single shot weapons such as DMRs, and especially with Shotguns.
 * The 14% extra damage makes dual wielding P30L's and DEagle 50's deadly rushing weapons in most scenarios. Combined with high adrenaline, It is nearly impossible to counter without luck and considerable accuracy.
 * Sustained fire from an LMG in open terrain is very effective, as the bullet spread guarantees hits and damage
 * Since this perk creates additional spread, it can cause inaccurate guns to be less effective at range
 * Small Arms
 * You are smaller than other players with this perk, use it to your advantage and move constantly.
 * Your faster speed makes you harder to hit with a melee weapon if they don't have adrenaline, keep distance if you engage in melee.
 * You can use the potato cannon with the perk because the increased speed wil allow you to move faster with it.
 * Takedown
 * Killing an enemy can heal some of the damage you received.
 * Useful in large battles as you automatically get healed after killing a player.
 * Combat Medic
 * Since it gives a speed boost when healing you can heal while running away.
 * When in a fight try healing up or using a soda and canceling to constantly have a speed boost
 * One with Nature
 * Camping in trees is very effective in ambushing players.
 * You will get a huge advantage in fights in bodies of water as instead of slowing you down the water speeds you up.
 * You can hide in trees while healing to avoid detection.
 * Scavenger
 * Getting this perk early can give you decent loot.
 * Be careful in shooting other players as you might accidentally break an obstacle and give them a weapon.
 * If your in need of ammo/weapons you can use this perk to destroy obstacles that have low health (bushes are recommended, very common and spawn in large quantities).
 * The Hunted
 * You can get high kill games as many players will target you.
 * Be careful as players might team up against you.
 * One in the Chamber
 * Very useful with accurate weapons such as Sniper Rifles.
 * Martyrdom
 * Players tend to rush and loot the person they just killed. Careless people tend to be killed by this perk.
 * Cast Ironskin
 * Useful in squads as you can shield your teammates and take reduced damage.
 * Make sure to hide in large obstacles as you will be easier to hit because of the increased size.
 * Bullets that bounced off can hit the enemy.

Against

 * Mass Medicate
 * This perk can be difficult to fight if the Medic is spamming Bandages and adrenaline supplies for nearby players, which can attack you in turn. Go for the medic when there are fewer enemy players nearby.
 * Grenades, especially MIRV Grenades, are extremely effective against a group of enemies huddling around a medic.
 * Especially useful when the Medic is reviving, as the Medic can't shoot while he's reviving other players.
 * Endless Ammo
 * This perk can be somewhat difficult to fight, especially in long battles, due to the Marksman will never run out of Ammo. Fight the Marksman as normal, but keep the fight as short as possible.
 * When the Marksman is hiding behind a ton of unopened Meteor Crates, flush him out with Throwables, especially Frag Grenades, MIRV Grenades, and Strobes.
 * Lieutenants are essential for going against Marksman, due to their gun last longer than usual due to the Firepower perk.
 * Try to use long-lasting LMGs for out-gunning the Marksman, like PKP Pecheneg and M249, or guns that do very high DPS, like the Dual P30L.
 * Splinter Rounds
 * Again, although the bullets again intimidating, it actually does 120% damage than normal. Fight them as normal, but higher-level Equipment and less time needed for fighting is recommended.
 * Try to take them on if you have a better Scope and a Sniper Rifle so you can pick them off easily and they cannot spray you with a high DPS weapon.
 * Try not to be shot by the middle bullet as it does more damage than the other 2.
 * Small Arms
 * The smaller size makes them harder to hit than in other players, be careful when engaging them and kill them quickly, their speed means that they can get away to heal up.
 * Takedown
 * The perk only acts when they get a kill so fight them as normal but avoid fighting them if they recently got a kill.
 * Combat Medic
 * Make sure to kill them quickly as they can get away with their speed.
 * One with Nature
 * Don’t go to close to trees to avoid possible ambushes and avoid fights in bodies of water.
 * Scavenger
 * Fight them normally but don’t go to places with many obstacles as they could get good loot to use against you.
 * The Hunted
 * Looking at the map can be used as an advantage as you can determine their exact location and movements.
 * Players would be targeting them constantly so the hunted would rarely be full health, best kill them while healing.
 * Note that they probably are experienced players so be cautious in engaging.
 * One in the Chamber
 * The bullet glows according to the type of ammo used so it is easier to see and avoid.
 * Constantly take cover and attack when they already shot the buffed bullet.
 * Martyrdom
 * Do not immediately rush to loot the enemy you just killed.
 * Cast Ironskin
 * Increased size makes them easier to hit but be careful as they take reduced damage and reflect bullets.

Trivia

 * Perks can now spawn as loot, but not with a circular loot border, instead it has a hexagonal loot border.
 * Perks were just images, names, and descriptions, while the stats are actually decided by the role you have. This was changed in the v0.7.95 "All you can shoot" update on August 9, 2019.
 * During the first woods event with the Shishigami no Kabuto, you could trigger the windwalk effect by being shot by a teammate.
 * Due to the cache spawning system, it is possible to acquire a perk from a Rock Cache from the normal map. This has been fixed on September 15, 2019.
