Doom Eternal is approximately twice the size of Doom 2016, according to executive producer Marty Stratton.

That would take the sequel’s campaign to in excess of 20 hours, based on the average 11.5 hours completion time of Doom 2016 measured by game length aggregation site How Long to Beat.

“It’s about double the size of Doom 2016,” Stratton said at a recent Doom Eternal preview event attended by VGC. “It’s the most epic and best thing that we’ve ever created at the studio.

“Our levels are bigger than they’ve ever been, we have double the amount of demons and from beginning to end you’re going to experience things that are always new.

“I refer to this as sort of the game version of a ‘page-turner’… even down to the last boss fight, you’re going to see things that you hadn’t up to that point,” he added.

The latest demo played by press was running on high-end PCs – read VGC’s new Doom Eternal preview – but Stratton claimed console owners are also in for “a real treat.”

“This game is, I think, the best technology we’ve ever made,” he said. “We’re at the end of a hardware cycle where engine teams really understand the hardware and are getting the most out of it.

“We’ve increased graphics fidelity, polygon count… everything is pushed in this game and it still runs on all the consoles that Doom 2016 ran on.

“It’s fantastic,” he added. “I can’t tell you enough about how good it looks on PS4 and Xbox. If you play on consoles you’ve got something really special to look forward to.”

Following a four-month delay, the Doom Eternal release date is March 20, 2020 for Xbox One, PS4 and PC.

Doom 64 is available as a Doom Eternal pre-order bonus on all platforms, including a Switch version which has yet to be dated.

Doom Eternal is available to pre-order at Amazon, Best Buy and Game, among other retailers.
