Hostile Survivors

A rules-light science-fiction survival roleplaying game set in a gritty, utilitarian retro-future. Players create ordinary characters shaped by their past triumphs and failures, then face situations involving war, catastrophe, alien horror, or isolation in orbit. A life-path system develops each character’s abilities, desires, and outlook through play. Survival depends on using the environment, available tools, ingenuity, and caution rather than relying on combat. Scenario templates cover a range of dangerous situations, and rules support both group and solo play. The game includes everything needed apart from six-sided dice and is compatible with other related rulebooks and supplements.
