Black Mesa is the fan-made reimagining of Valve Software’s Half-Life.
You are Gordon Freeman, a theoretical physicist at the Black Mesa Research Facility. When a routine experiment goes horribly wrong, you must fight your way through an interdimensional alien invasion, and a bloodthirsty military clean-up crew in order to save the science team... and the world!
Venture into a completely reimagined and refined single player campaign, including all new and expanded Xen levels with 19 chapters of fighting through top-secret labs, running atop harsh desert landscapes, sneaking into abandoned railways, and leaping across dimensions.
Face off against an army of classic enemies, updated with new features and engaging AI as you wield an arsenal of military hardware, scientific prototypes, and the iconic crowbar through incredibly detailed environments.
The all-new soundtrack and voice acting pair with mind-Blowing graphics and effects, never before seen on the Source Engine, to create a more immersive experience than ever before.
