how do you start the game black mesa

how in the hell you even start this game? where is the EXE located at? I have downloaded HL2 once again, and I still cannot get this game to even start. I downloaded the SDK version but with out an exe I cannot do anything.

You will need the installator and blackmesa.7zip.

You must have Source SDK 2007.

If you don’t have installator, extract blackmesa.7z into steamapps/sourcemod/BMS (it must be BMS!). Than - restart steam. Black Mesa should appear on your games list.

Thank you, it finally updated in steam.
