Scavenger (perk)

Scavenger is a Tier One Perk appearing in Call of Duty: Modern Warfare 2, Call of Duty: Black Ops, and Call of Duty: Modern Warfare 3, a Tier Two perk in Call of Duty: Black Ops II, and is scheduled to appear as an awareness perk in Call of Duty: Ghosts.

Call of Duty: Modern Warfare 2
In Modern Warfare 2, it is unlocked at level thirteen. Scavenger resupplies one primary magazine, one secondary magazine, one piece of equipment, one special grenade, one Grenade Launcher grenade, and/or four Shotgun attachment shells when Scavenger packs dropped by player's corpses are picked up, regardless of any loadout differences between the player and the dead player. This perk also acts as a replacement for the ammo perks from the other games such as Bandolier and Frag x3, since it allows the player to restock on equipment.

Uses
With Scavenger, bodies will still drop weapons. Running over a weapon that utilizes the same caliber and magazines as the current weapon will not pickup ammo unless the weapon has the same attachment as one in use. For example, if using an M16A4 and running over an M16A4 with FMJ, ammo will not increase. Indeed, even picking up a camouflaged M16A4 will not increase the ammo for a standard M16A4. The player will instead have two separate ammo counts. Well-organized teams consider standardizing their weapon camouflage and attachments to facilitate ammo transfer.

Scavenger is usually the preferred perk in the first tier slot amongst players with higher killstreak setups. This is most likely because players need more kills before obtaining any killstreaks, which necessitates the need for more ammo replenishment.

Pro Version
The Pro version of Scavenger is unlocked once a player has resupplied 100 times while using Scavenger. Scavenger Pro allows the player to spawn with full ammo for the weapons he or she has, replacing the Bandolier perk from previous games.

The Pro version is not always useful, since ammo can be resupplied without it. However, Scavenger Pro is most useful for players who spend a long time distant from action, since their opportunities to resupply will be few and far between; the increased starting ammo count will permit them to extend their stay at the location of their choice.

Call of Duty: Black Ops
Scavenger returns as a Tier 1 perk in Black Ops. While its function is largely unchanged, some fine points have been tweaked.

Overview
Scavenger allows the player to see and pick up ammo bags left by dead players. These bags replenish one magazine of ammunition for each weapon the player carries and one lethal grenade. The Pro version allows the player to pick up one tactical grenade with each bag (excluding the Willy Pete smoke grenade) and spawns the player with maximum ammo.

Notably, Scavenger no longer replenishes weapon attachments, launchers and most equipment. If a certain amount of bags are picked up, the only pieces of equipment it is known to resupply is the Camera Spike and the Motion Sensor.

Scavenger is great for players using SMGs with small ammo capacity, like the Kiparis or the Skorpion, as the 4 total magazines can be expended quickly. It is also useful for players wishing to attain higher killstreaks, as more ammunition can be used to gain kills without worrying about running out of ammo.

Pro Challenges

 * Resupplies — Resupply 150 times while using Scavenger.
 * Grenade Kills — Get 5 Lethal Grenade kills with a resupplied lethal grenade.
 * Kill Count — Get 5 kills without dying, 5 times.

Call of Duty: Modern Warfare 3
The Scavenger perk replenishes one magazine of ammo for every Scavenger pack picked up. The perk is unlocked at Level 39 in Multiplayer. Scavenger no longer replenishes Lethal equipment like Frags and Semtex or Tactical equipment like Stuns and Flashbangs. It also does not resupply grenade launcher ammo, just like Black Ops. However, Throwing Knives and Underbarrel Shotguns can still be resupplied.

Its Pro Effect allows the player to spawn with extra magazines. Like in Modern Warfare 2, the Pro Perk is unlocked when the player resupplies by picking up a total of 100 Scavenger Packs in Modern Warfare 3. This is widely regarded as one of the easiest Pro Perks to unlock.

Call of Duty: Black Ops II
"Replenish ammo and equipment from enemies killed by non-explosive weapons."

- Create-A-Class Description.

Scavenger returns in Call of Duty: Black Ops II. It lets the player pick up ammo packs that are dropped by enemies that were killed by non-explosive weapons to replenish ammo and equipment. Lethal and tactical equipment are now resupplied, along with rocket launcher ammo. However, grenade launcher rounds are not.

This perk is often used with C4, allowing for formidable explosive offence, potentially many times in each life. It is also very useful with tactical grenades, such as Flashbang or Concussion grenades. A player using Scavenger, Fast Hands, C4 and Concussion (or Flashbang) grenades is well equiped for a mobile, offensive style of play, especially on CQB environments.

Call of Duty: Ghosts
Scavenger returns in Call of Duty: Ghosts as an awareness perk. It functions similarly to the version from Modern Warfare 3, as it does not resupply tactical or lethal grenades, only ammunition.

General

 * The sound of a bag opening is heard when picking up ammunition.

Call of Duty: Modern Warfare 2

 * The Scavenger bags left by enemies are only picked up when the player is in need of ammunition for the currently equipped weapon, equipment, or special grenades.
 * In Hardcore game modes, a hit-marker (x) appears when a Scavenger bag is picked up instead of the Scavenger icon. Same goes for Call of Duty: Modern Warfare 3.
 * The in-game description for this perk is wrong, as the player can resupply from dead allies and their own dead bodies along with enemies' dead bodies.
 * With fragmentation grenades, the player can actually get a second fragmentation grenade from a Scavenger bag. This only works with fragmentation grenades.
 * Completing the challenge Scavenger Pro: VI will give the player the title "Vulture."
 * The Scavenger Bag itself has a picture of a vulture on the side, like that of the perk picture.

Call of Duty: Black Ops

 * The player will always pick up a Scavenger Pack, even if the player has full ammo for all weapons.
 * A Scavenger pack can be found at the start of the Executive Order campaign mission.

Call of Duty: Modern Warfare 3

 * When refilling with Scavenger in the Wii version of Modern Warfare 3, it shows the Modern Warfare 2 scavenger picture.
 * Scavenger Pro does not increase starting ammo if used in a Specialist Strike Package, even when the player spawns on the next round.

Call of Duty: Black Ops II

 * This is the first game where the perk icon for Scavenger is not a vulture.
 * It is also the first game where it is not a Tier 1 perk.
 * Like other perks, the pro version is not present in this game, so there is no way  to spawn with full ammo for the starting weapons, unlike in previous games.
 * In Nuketown Zombies, one of the zombie models resemble the Black Ops Scavenger player models.
