Prior to Dead Space 3's release, a report indicated Electronic Arts wanted to move the series away from the survival-horror genre once the Dead Space trilogy was complete.[7] During production of Dead Space 3, the team created story and gameplay concepts for the next game, which would have focused on the protagonist scavenging to survive as humanity neared extinction; Wanat envisioned the protagonist as Ellie rather than Isaac. The gameplay would have expanded upon the open, brief, zero-gravity sections in Dead Space 3, redesigned the Necromorphs to work in zero-gravity environments, reworked the crafting system, and incorporated a variety of ships to explore. There was also a concept for the Necromorphs' origin and the measures humanity might have to take to avoid extinction.[8] Ultimately, plans for a fourth Dead Space game were abandoned as the team disbanded to work on other projects.[9][8] Wanat had material planned for up to an envisioned fifth game.[10]
