Pulse myths

Pulse stops vertical (he holds the hatch). He doesn't block a hatch or a hammer; he finds attackers above and punishes them. His anti-vertical is intel plus a Nitro Cell, not denial.

Key Pulse facts (Y11S3)

Detects attacker heartbeats within 9 m through walls and floors; Finka-boosted attackers show up to 14 m; Pulse can't shoot while it's up. (since current (no change found through Y11S3))
The sensor is 'more useful vertically than horizontally', e.g. plant denial from the floor below with a Nitro Cell.
Heartbeat detection still finds Nokk with HEL active, and Sledge or other vertical players like anyone else.
Electronic: IQ locates Pulse while the sensor is out; Thatcher's EMP freezes the sensor for a few seconds.
Ubisoft pairs Tubarão with Pulse or Solis for 'defending from below'; guides rate Pulse as Noor's strongest partner for blind lance shots. (since Y8S4 / Y11S3)
