Motion sensors drain energy from enemies when tripped, and provide a warning when tripped or destroyed. If tripped by an enemy player, they also deal 10 damage to them. Technicians can deploy up to 3 motion sensors at a time (4 with the Safety Third perk). Once deployed an icon will appear in the bottom left of the player's HUD until the sensor is destroyed.
Unlike Mines which are usually hidden to cause damage to enemies, Motion Sensors are typically placed in open areas that enemies must pass through in order to reach an objective. This forces the enemy to either set off the sensor or destroy it, which also sets of the alarm. Motion Sensors also temporarily reveal Infiltrators from stealth and Raiders using the Jammer Pack . For this reason they are often placed next to Light Turrets to prevent Infiltrators from Melee Striking them to death or walking past them.
Sensors can also be deployed around the flag to drain energy from cappers when they grab, making their getaway more difficult.
