Participants in the beta test of shooter Modern Warfare 4 have discovered a unique ISO Trace weapon modification for the ISO Nightshade submachine gun that allows you to track enemies through walls.
The special Apex mod uses a special RFID cartridge that displays a tag on a small screen below the crosshair when it hits an enemy. This allows players to instantly see the movements of their opponents ahead, turning an ambush firefight into a controlled hunt.
To unlock this feature, players will need to upgrade their submachine gun to level 56 to take advantage of the double experience bonus available in the beta. Experts point out that this mechanism can fundamentally change not only the balance of online matches, but also the balance of Warzone Battle Royale.
