Today, via Twitter, Microsoft’s Major Nelson announced that Dead Space Ignition and Escape Dead Island have joined the Xbox One Backwards Compatible Lineup.

For those unfamiliar with the two, here are some handy-dandy overviews:

Escape Dead Island:

Escape Dead Island is a Survival-Mystery game set on the enigmatic island of Narapela after the events of the zombie outbreak of the original Dead Island. The story lets players unravel the origins of the zombie virus through the eyes of the would-be documentary journalist Cliff Calo. There are no superpowers to keep Cliff alive, just a few makeshift weapons against hordes of infected zombies. It will be integral to choosing wisely between stealth and combat at certain moments in the game.

Dead Space Ignition

Dead Space Ignition combines an interactive comic-style story with three unique hacking mini games; Hardware Crack, Trace Route and System Override. Each game offers a fun and satisfying arcade experience that will challenge players with puzzles and twitch gameplay. Dead Space Ignition features a unique. Choose Your Own Adventure type narrative, allowing players to survive the horrific Necromorph outbreak in multiple ways. The game offers four unique endings and upon completion of each one, players will be rewarded with unlocks including an exclusive suit, all of which can be used by Isaac Clarke in Dead Space 2
