According to Dylan Cuthbert, president and executive producer at the studio, the genre-bending PlayStation 4 exclusive will likely be available in Fall 2015, which means between September and November.
Revealed during Gamescom 2014, The Tomorrow Children combines shooting, world-building, resource gathering and management, tower defence, strategy, and multiplayer co-op.
Cuthbert said the team has been "adding tons of new features previously unseen in trailers and the closed alpha last fall" and "enriching the story and setting."
"Although the world of The Tomorrow Children is encased in the bleak Void, life still flourishes as humanity claws its way back from the brink of extinction, and players in the roles of Projection Clones will take that life into their own hands," Cuthbert explained.
"Players will take control the fate of their town and eventually the world itself as they build up and expand it from a nearly empty outpost into a lively home filled with shops, facilities, and even a home of their very own, all while defending everything they’ve built in life and death struggles with invaders from the edges of existence."
