Echo Pulse

Echo Pulse is the Recon Runner Shell's Prime ability in Marathon. When activated, it emits sonar pulses outward from the Recon's position that reveal the locations of nearby enemies, displaying their positions to the Recon and their squadmates even through walls and solid cover. Critically, Echo Pulse can detect invisible runners including those using the Assassin's Active Camo, making it one of the few hard counters to stealth-based Runner Shells in the game.

Echo Pulse has a cooldown of approximately 5 seconds, making it a frequent-use ability that can provide near-constant map awareness when timed well. The intel it generates is immediately actionable for a whole squad, turning a Recon player with good timing into a real-time callout machine. In competitive play, Echo Pulse is particularly valuable before pushing through doorways, entering buildings, or moving through areas where enemies might be waiting in ambush. Pairing Echo Pulse with Stalker Protocol and Tracker Drone creates a comprehensive package of detection, marking, and harassment that can lock down an entire area of the map for the Recon's team.
