The Aperture Mesa Incident

This is a mod being created by MLSTRM.

It is set in the time period after the end of Portal with Aperture science activating an "Emergency Protocol 1" which starts a nuclear bomb launch sequence that would destroy everything, that is aimed at Black Mesa.

The story will be split into two storylines "A" for Chell and "B" for Gordon Freeman, you can play the storylines independently and complete them independently but the final credits will only be shown after you complete both.
