Outpost Simulator, a survival craft FPS from developer Mental Dreams, is in a pre-launch phase with a playable Steam demo released on August 21, 2026. The demo covers base building, survivor management, raid defense, and early story content, with the developers planning map expansions, seasons, and deeper raids before full launch.
Outpost Simulator is a survival craft FPS from developer Mental Dreams, published by Ultimate Games and Ultimate Publishing. The game casts players as the manager of an outpost for survivors in a monster-overrun world, where they gather materials, trade at a market, and defend against raider attacks.
A Steam demo released on August 21, 2026, and it covers the core loop: outpost construction, survivor care, raid defense, character growth, and early story content. The demo includes a tutorial with the story prologue and supports Japanese. The team is actively seeking community feedback, and the in-game menu outlines future updates, including map expansion, seasonal changes, and more involved enemy raids.
The two stories, published days apart, present the demo as the key early look at the full experience. The later story frames the published update plan as evidence of the developer's intent to broaden the map, add seasons, and deepen raids before launch. No release date for the full game has been announced in either story.
