Weapon Case Events Explained
In order to obtain the prestigious Biohazard skin, players will need to completeseven Weapon Case Eventsby successfully extracting with the Weapon Case. These events most commonly spawn near the Observatory, the Al Sharim Pass, or Zarqa Hydroelectric, but can be located on the mini-map by looking for a large yellow area with a briefcase.
Here are the rewards for completing each Weapon Case Event:
Once players enter the yellow zone, they should start toeliminate enemy AIsuntil they hear an announcement that a heavily-armored enemy unit (Juggernaut) has entered the area. Players will now have to defeat him to obtain the Weapon Case, preferably withone of the many top-tier LMGsavailable to use inCall of Duty Modern Warfare 2. As soon as a player equips the Weapons Case, they’ll be marked on the map and all players will be able to see exactly where they are similar to the Most Wanted Contract fromWarzone.
Tips to Successfully Extract with the Weapon Case
Now that players have a huge target on their backs, they’ll need to get to an Exfil Helicopter quickly. But, it’s best not to use one of the marked Exfil Choppers since other squads will know exactly where to set up an ambush. The best way to exfil is to complete a Hostage Rescue contract, since it’ll call in an unmarked Extract Chopper. But, of course, players will need to ensure they are quick since other players will be on their way to steal the Weapon Case.
Players can also prepare beforehand by equipping a 3-Plate Armor Vest and having Self-Revives (or even the new Revive Pistol). Additionally, players can purchase a UAV (or complete the UAV mission) to scan the area and avoid encountering other players. Once extracted, the entire squad will receive the Weapon Case reward. Once they complete the seventh one, the Biohazard operator skin for Konig will be unlocked.
