Dead Space 4 was the planned fourth installment in the Dead Space series.
The game would have followed on directly from Dead Space 3 with humanity facing extinction at the hands of the Brethren Moons. Taking inspiration from the flotilla section in Dead Space 3, the notion was that the player (Ben Wanat stated that he would have made Ellie Langford the game's protagonist) was trying to survive on a day-by-day basis, scavenging supplies while looking for survivors and withstanding the Necromorph infected ships. The player would have their own ship. It was intended that the ships would be diverse, each with unique purposes, floor plans and gameplay.
The game would utilize non-linear gameplay, being a hybrid between the chapter format of the previous games and the new, non-linear style. An idea floated around was that the player would start off in a section of space, follow a trail of carcasses to an abandoned space station and scavenge fuel and a ShockPoint Drive. The retrieval of the drive would make their ship shock-capable, allowing them access to the new sectors of space. The elements of the plot would be uncovered as the player explored new areas. As the game went on, the range of exploration would be greater.
For the weapons, it was indicated that the crafting system of Dead Space 3 would be re-examined. New Necromorphs that could function in zero-g would be introduced.
The ideas for the game are mainly confined to Visceral Games' story team. While they knew how the game would end, Wanat refused to give the ending away in case Electronic Arts returned to the franchise. He provided hints by stating "I did not want to give the lore away, but I would say that we spent a bit of time working the origin of the Necromorphs out and what purpose that the humans held in this dark universe. Would the players find a way out of the Necromorph apocalypse? I would say yes, but they might be sorry that they did. Sometimes, you are better off with the devil that you knew."
Ultimately, the game was never produced as Visceral Games moved on to the other projects and was later shut down.
