Black Mesa (Source)/Unforeseen Consequences

For the original Half-Life version, see this page.

Unforseen Consequences is the third chapter of Black Mesa.

It takes place in a destroyed version of the anomalous materials labs.

Overview

The player must traverse the previous chapter, Anomalous Materials, but in a destroyed state. Unlike the original, the player receives the crowbar later in the chapter and can use flares to set zombies alight.

NPCs

Like Anomolous Materials, the player can find Scientists and Security Guards, but can also encounter Headcrabs and Zombies.

Plot

After the resonance cascade, Gordon Freeman must get topside to let someone know that the science team is stranded.
