Doom Eternal Update 6.66 brings Horde Mode next week

Doom Eternal is about to get one of its most substantial updates yet with the long-awaited arrival of Horde Mode coming later this October.


Id Software has some goodies up its sleeve this month. Doom Eternal is about to hit Update 6.66 and if you’re going to be the hell-slaying arriving at an Update 6.66, you might as well make it a big update. It would appear that is exactly the case for Doom Eternal. Id Software is not only bringing Doom Eternal a Battlemode 2.0 edition and several new master levels, but a much-wanted Horde Mode that will allow you to take on the waves of hell for as long as you can and prove yourself among the best Doom Slayers in the world.

Id Software and Bethesda announced the details of Doom Eternal Update 6.66 via the Doom official Twitter on October 21, 2021. According to the tweet, Doom Eternal’s Update 6.66 is scheduled to roll out on October 26, 2021, next week. With it will come improvements to Battlemode, dubbed Battlemode 2.0. The game will also get two new master levels to play and the arrival of Horde Mode. What’s more, id Software is set to show off the Horde mode in a livestream.

      this would be the perfect time to introduce a surprise co-op mode.

        Given the way the game uses time dilation both for glory kills and also any time the weapon wheel is open that'd take some real work.

          they must have a solve for that though? there's already MP, it's just that dumb player vs demons mode. in fact, that's even more difficult because it's competitive.

        Definitely not gonna happen. A Horde style would have been a great opportunity for coop in nu-Doom finally, but from the start they labelled it with the oxymoronic "Single Player Horde Mode."

        Like, it's fine if there's a horde mode that can also be played solo, but wtf, id. Why make one solo on purpose when coop has always been the draw for those? idgi.

        i hope this comes with a big TAG sale. i could go back to that ball-busting masochist machine, i think.

          They nerfed TAG1 a bit and IMHO TAG2 isn't tough at all. Master Levels are definitively where the real challenge is now. The last two they did are just so nasty lol

            yeah i'll just go pound nails through my dick instead, thanks.

            i did eventually learn to love eternal, but it was more a matter of survival and not "let's see how bad this can get".
