Throughout the game, players traverse a variety of areas within Black Mesa, facing numerous challenges, solving puzzles, and battling both alien and human foes. Here are the key areas players encounter:

Unforeseen Consequences: The aftermath of the Resonance Cascade leaves the facility in chaos, with players navigating through damaged infrastructure and battling headcrab-infested zombies.
