Black Mesa - Improved Xen Mod

Black Mesa - Improved Xen mod from the Steam workshop.

This mod is NOT an improvement over Black Mesa's vanilla Xen, it is an improvement over classic Half-Life's Xen. This mod essentially remakes all of the Xen levels from Half-Life Classic, with the graphical fidelity of Black Mesa's Xen levels. Black Mesa's Xen is far superior from this mod, however it takes many, MANY creative liberties in terms of levels, almost unrecognisable. If you want an upgraded version of Half-Life 1's Xen, this is your mod. If you want an incredible, beautiful scenic, but dramatic and eventful trek through a hostile alien planet, Black Mesa's Xen is the way to go.
