2016's Doom and the original Rage are now both available via Xbox Games Pass - their arrivals timed to coincide with this weekend's QuakeCon 2018 festivities.
It's especially well-timed as publisher Bethesda and developer id Software have spent the weekend chatting about both games' upcoming sequels: Doom Eternal and Rage 2.
This weekend we learned Rage 2 won't have multiplayer but will have "a social component", then saw our first look at Doom Eternal gameplay and found out it would also launch for Nintendo Switch.
