No matter which way you choose, get ready for adrenaline-pumping, action-packed excitement that's sure to give your heart a real workout.
Astrostein is a DOOM II scenario made by Laz Rojas. It features a storyline taking place in an alternate future, where Nazis conquered weapons from the future via a time portal and won WWII. 10 levels are featured. Astrostein would influence quite a handful of mods in the wake of its release, and it remains a highly respected and imaginative piece of work.
This MOD should be about the soviet Union instead... They were real villains.
