Unofficially if you Pre-order DOOM you will get Doom one and two via backward compatibility

There has been a picture cycling around on the internet about the new DOOM.

As you can see above here it says that if you pre-order DOOM you will also get Doom one and two. It also says that you will get the Demon Multiplayer Pack. Xbox nor Microsoft have not officially announced this and it seems like the picture was quickly taken down. I have done some research about what DOOM has to offer but alas I found no information about getting Doom one and two. I could however, tell you what you can definitely get if you pre-order the game and some extra details.

Created in conjunction with Triforce, the DOOM Collector’s Edition includes an exclusive, fully-realized 12” tall collector’s statue of one of DOOM’s most iconic demons: the Revenant. Made of high-quality PVC and modeled from actual in-game 3D files, the Revenant stands on an LED-lit base with internal, slow-spinning turbine from the UAC facility on Mars. The DOOM Collector’s Edition also includes the highly-anticipated game, packaged in an exclusive metal case.

DOOM will be available to play on PC, Xbox One, and PlayStation 4.

I think that many fans would be pleased to hear if they could play Doom one and two on the Xbox One, of course you can purchase them right now but that wouldn’t be the same.
