"Shephard, you're alive! Listen, we've been cut off pretty bad and orders are coming down to pull out. Repeat: Pull Out! Heard they've got other plans for Black Mesa now. If you can make your way through the transit system you can probably reach the surface where we are pulling out. Good Luck! Over."
―HECU Officer[src]

Radios are used by the HECU during the Black Mesa Incident to communicate within the Black Mesa Research Facility.


Commonly found at choke points or camps, it gives the HECU insight on the battlefield and status on squads or camps. Gordon Freeman, Adrian Shephard, and Barney Calhoun use them to listen to the HECU's tactics and next moves. Shephard will often use radios to gain vital information on other soldiers' whereabouts and what his next move should be.

Radios commonly come with one or two antennas. Gameplay wise, it informally precedes the Resistance radios featured in Half-Life 2 and its episodes.

As a HECU Marine, Shephard cannot destroy any radio, while the other playable characters can.


  • The texture for the main panel of the radio is also used throughout Black Mesa for generic control panels.
  • All radios, (except for ones vital to gameplay) will break with 3 hits from a crowbar.
  • The radio appear in the map de_nuke, as_forest,cs_docks,and cs_iraq in Counter-Strike. However, it just a simply a prop and it cannot be destroyed or used.
