Roamers (Caveira, Jager, Vigil, Alibi, etc.): Pulse's intelligence gathering is particularly powerful when paired with clear communication with roamers.

Jackal and Dokkaebi's anti-roaming gadgets naturally make this harder. Dokkaebi & Jackal (Soft Counter): To get around a somewhat weak loadout, Pulse often relies on staying undetected and ambushing enemies.Twitch (Soft Counter): If Pulse is using the Cardiac Sensor as Twitch zaps him with her drone, the sensor will briefly glitch before returning to normal.Thatcher (Hard Counter): If Pulse is within the radius of Thatcher's EMP grenade as it detonates, the Cardiac Sensor will be disabled for a few seconds.Pulse can only detect IQ's heart up to 10 meters away, so she naturally has the upper hand if both gadgets are in use. IQ (Soft Counter): IQ's electronics scanner can see Pulse's Cardiac Sensor through any surface while its in use, up to 20 meters.No matter how quiet she's moving, her heart will be seen by Pulse. NР“С‘kk (Soft Counter): NР“С‘kk's HEL Presence device is designed to counter every information gadget defenders can throw at her, except the Cardiac Sensor.During this period, Pulse can see attackers on the Cardiac Sensor from farther away than usual. Finka (Soft Counter): When Finka uses an Adrenal Surge on her whole team, the hear rates of those affected speeds up.All Attackers (Soft Counter): If they have a heart, Pulse can see it.Pulse's Cardiac Sensor gives him unique opportunities to combo with the nitro cell (more on that below). As for secondary gadgets, nitro cell is almost always the superior option. Thankfully, the 5.7 USG is a reliable and laser-accurate backup. His M1014 shotgun is a useful for creating rotation holes or opening hatches, but its accuracy and damage are on the low end of shotguns. This makes it one of the most controllable weapons in Siege, but also comparably weak, especially at long range. His primary weapon to most players, the UMP45 SMG, has a low DPS brought about by an especially low fire rate. Pulse's impressive information gadget is balanced by his limited firepower. As a roamer, he can be useful in all the same ways, though his weapons aren't optimized for long range engagements down hallways. The Cardiac Sensor is a great companion for shooting through walls, which makes Pulse better than most operators at contesting an objective from a floor above or below.

No attacker can avoid being scanned by the Cardiac Sensor if they're close enough, so Pulse is very useful for informing his teammates when enemies are close to the objective, and which route they'll likely take. Pulse excels as an anchor or roamer, but he's best played closer to the objective (be that on the same level, or above/below it). The sensor does not detect friendly heartbeats.

Equipping and unequipping the sensor leaves Pulse helpless for a brief moment. When the sensor is equipped, Pulse cannot use any weapons or sprint. Every few seconds, the scanner automatically pulses and updates the locations of any heartbeats it detects. Pulse wields a handheld Cardiac Sensor that can detect enemy heartbeats through all surfaces.
