Hacker makes all enemy equipment, Sentry Guns, and SAM Turrets glow bright red to the player. The glow is visible through most surfaces and from any distance.
Its Pro version also automatically booby traps enemy Care Packages when stealing them (causing them to explode when the enemy tries to claim them), allows the player to make enemy killstreaks (i.e. Sentry Gun and SAM Turret) and equipment attack the team that placed it, and makes the player undetectable by enemy Motion Sensors. It takes three seconds to hack enemy equipment/killstreaks. When hacking an enemy Care Package the player will capture the package normally; in addition, a decoy package (possessing skull-and-crossbones motifs) will appear in its place. The decoy will appear as a random killstreak reward to the enemy, and as soon as a player attempts to capture the booby trapped Care Package it will detonate, killing the person who set it off and any other nearby enemies. When hacked, the Care Package will change color from red to black from the hacker's team's perspective. The downside to hacking Packages is that killstreak icon above the Care Package will switch for the person who received and threw the marking grenade, making a hack possible to detect unless the player isn't paying attention to the icon (i.e. the Spy plane icon may switch to a Sentry Gun icon once booby trapped). When a player hacks enemy equipment/killstreaks, that piece of equipment will become friendly to the player and his team, but they will be unable to pick it up and reposition it. When a player hacks a Camera Spike, they will gain control of the camera's feed but they will be unable to toggle between the feed and the mini-map.
Should the player hack an enemy equipment, their own equipment (if not used yet in that life) cannot be used until the hacked item is destroyed or the player respawns since only one equipment can be used. Likewise, if the player places a piece of equipment then hacks another user's equipment which is the same as the player's placed, their original equipment will be destroyed. For example, if they place a claymore then hack a claymore their original claymore will explode. However, if the player hacks a different piece of equipment than the player has, both will function.
