The Pulse SMG is a weapon featured in Half-Life: Alyx. It is a Dark Energy/pulse-powered sub machine gun manufactured by the Combine.

It vaguely resembles the OSIPR, and appears to share the same "pulse-plug" ammunition (and loading mechanism).


An unmodified SMG holds a 30-round pulse plug that must be reloaded manually by pushing it into the left side. The extended magazine holds three additional pulse plugs, and each one must be inserted manually. By default, it has no sights.


  • When the extended magazine upgrade is equipped, it has what looks like a Energy Ball launcher similar to an OSIPR, but it cannot be used by the player.

The SMG has 3 upgrades:

  • Reflex Sight-cost 15 Resin
  • Laser Sight-cost 25 Resin
  • Extended magazine-cost 30 Resin
