Final answer:
Cypher's Spy Cam ability in Valorant reveals enemy players for 3 seconds once tagged. The reveal duration can be shortened if the enemy removes the dart from themselves.
Step-by-step explanation:
The duration Cypher's Spy Cam ability reveals the location of enemy players in the game Valorant is 3 seconds after an enemy has been tagged by the camera's dart. This ability is a tactical tool that Cypher can use to gather valuable information for his team. It's important to note that the revealing effect will only last as long as the dart remains in the enemy, as they have the option to remove it, cutting short the reveal effect.
