HLFX: Lost in Black Mesa

A singleplayer mod for Half-Life based on a new version of Half-Life FX Graphics Add-on. It consists of three gameplay levels.

You will visit a laboratory complex and a part of Black Mesa monorail transit system. Similar to the HLFX: Single demo version, you will face doors with keypads and have an opportunity to manually delve into electric wiring, restoring the power for some systems.

Do not forget that Black Mesa complex is way too large, so there are some secret places in the game that are not accessed easily. Upon revealing a secret the game will show how many places like that are on the level, and they are on each level. So keep your eyes open!
