GameStop is currently offering one of the best deals we have ever seen on id Software's new Doom.

The store is now selling the first-person shooter for only $20 across PlayStation 4, Xbox One, and PC (via NeoGAF). Bear in mind that this price is for a physical copy, not a digital one, if that matters to you. GameStop also sells digital codes for Doom, but those are priced at $60. There is no word on how long the new deal will last, so if you're interested, you may want to act quickly. Go to GameStop's website to place an order.

Doom launched in May and was generally well-received, getting a score of 8/10 from GameSpot.

"Doom is the product of a tradition as old as shooters, and while it's not the model to follow in every case, modern shooters could learn a thing or two from Doom's honed and unadulterated identity," reviewer Peter Brown said.

Publisher Bethesda has not announced a sales figure for the game, but it was the No. 2 physical title in the US for May 2016 behind only Uncharted 4: A Thief's End, according to NPD.

Doom's first multiplayer DLC, Unto the Evil, launched earlier this month on all platforms for $15. The game also continues to receive new, free content. One such update arrived a few weeks ago and added two new modes and SnapMap functionality.
