Now that Call of Duty: World War 2 has finally been released and players are making their way around the battlefield, a new hidden feature has been unearthed.
A load of '80s retro games have been added to the new release, and we're loving them already.
So, if all the shooting is getting a bit much, you can head over to the Headquarters social area to switch off for a bit and play the old-school games which can be found in the R&R section.
And they're pretty decent vintage Activision games too, so it's a great addition to the title.
The full list of games is: Barnstorming, Boxing, Chopper Command, Cosmic Commuter, Demon Attack, Enduro, Fishing Derby, Grand Prix, Kaboom!, Pitfall II, Private Eye, River Raid, Seaquest, Skiing and Spider Fighter.
To have a go at any of the above, armoury credits earned via the main gameplay can be used in exchange for all the fun.
The feature has gone down pretty well with those who've already had a go.
