At the start of this month, digital sales site Bundle Stars rebranded itself as Fanatical. It's since launched a number of deals packages—such as the Max Damage and Curve Digital bundles—and now turns its head to id Software's hell-set demon shooter Doom. 

Tier one of Fanatical's Doom Bundle discounts 2016's Doom reboot by 67 percent, selling for £6.66/$9.99 alongside all of its add-ons and DLC. Tier two, if you're feeling flush, adds Doom Classic Complete and Doom 3: BFG Edition into the mix for £13.84/$19.99. Note that it's not possible to upgrade from one tier to the next after purchase, so bear this in mind before splashing out.
