Characters

Playable scientist
Gordon Freeman
A Black Mesa researcher wearing an HEV suit when the experiment causes the resonance cascade.


Civilian allies
Black Mesa scientists
Researchers can open secured routes and sometimes provide medical help.


Military enemies
HECU marines
Human opponents use gunfire, cover and grenades throughout the facility.

Quick notes
- Know who Gordon can work with. Gordon is a scientist forced into combat, and the surviving Black Mesa staff are more than background scenery.
- Separate allies, invaders and the military. The resonance cascade brings Xen creatures into Black Mesa, while the HECU arrives as a hostile human force.
- Watch the G-Man without expecting an explanation. The G-Man appears behind glass, on distant walkways and in other inaccessible positions.
- Keep sequel identities out of the first campaign. Many original scientists and guards use repeated models and generic roles.
