Short and intense map where you will be in a military base and then take a walk through hell and little by little look for keys and discover the secrets of a base that has been taken over by the demons they experimented with.
The wad runs in files like gzdoom, zdoom, lzdoom and many more normal doom launchers. It's just one level. All the information of the permits, music, dates and other technical things are inside the zip in the .txt file :)
It is easy to install, first you download the .zip from here, then you extract it in the place you want, the .zip has 2 files inside, a .txt with all the information of the wad, and the wad itself, that to be able to execute it correctly you must drag the wad to the doom launcher that you have the most or prefer, to be able to run it you have to select DOOM 2 afterwards, if you don't have it, what you have to do is first have the doom launcher that you want and then inside from the same folder put the wad of DOOM2.wad.
If you have done all this, by dragging the Hangar18 wad into the launcher and selecting DOOM2, you will be able to play it perfectly
