If you're looking for an excuse to dive back into Doom Eternal, you might want to check out the freshly launched Update 6.66 as it's quite the meaty one. Not only has it added a Horde Mode with a wide assortment of challenges to overcome, but it has also overhauled Battlemode, added two new Master levels, brought in new cosmetics, added a new multiplayer arena, and the list goes on for a while.

The way the Horde mode works is fairly simple. You'll start each run with all perks, runes and mods already upgraded, though you'll only have a Combat Shotgun at your disposal. As you slaughter your way through hordes of enemies you'll receive other weapons and acquire a whole bunch of points that can be used to either brag on the leaderboards or to unlock some fancy new cosmetics. And once you've proven your mastery over the demonic hordes, you can increase the difficulty and go for even greater conquests.

What all of this looks like in actual gameplay, however, that you can find out through the recently posted trailer. Have a gander, it's quite a fun one:

As for the rest of the changes, they are far too varied and numerous to easily summarize. So if you're curious about all of the minute details behind Update 6.66, you should hop on over to the official patch notes.

Enjoy, and do make sure to grab a cup of coffee before you dive in since you'll be stuck there for a while!
