The culmination of over 2 years of work and many sleepless nights is now ready for you to enjoy and hate. As with the earlier 2 releases, this third one manages to create a world unparalleled in complexity and interest. Then take a tour of the Credits level and see all the folks who were involved in making this product what it is.
Installation is simple.
Way more than 6 savegame slots, and it'll handle launching the demos that are coming soon, with ease. If you have Eternal II, then the upgrade will handle changes to the existing levels, texture updates, addition of the new levels, improvements to existing music as well as all new music for the new levels. If you don't have Eternal yet, carve out a year or so to play, download the full package, and get going. Try to remember to do your taxes when that date comes up, and look up once in a while to see if you have any family or friends left. But because it was a second release, it's also been called Eternal DOOM 2.
