Crash on Planet X

m
maxtyl

Your ship has crash-landed on an uncharted planet. There are no signs of civilization—only an endless, hostile wilderness teeming with lifeforms that don’t fear you, they hunt you. The atmosphere is barely breathable, storms rage unpredictably, and the native ecosystem is as beautiful as it is lethal. No backup, no escape route. You must survive with what’s left of your ship, scavenging and adapting to a world that does not want you here.


Author's Note: - Genre: Hardcore Survival Horror / Sci-Fi Wilderness Exploration - Atmosphere: Vast, oppressive, alien. The planet is untouched by civilization. Towering predatory flora, violent weather patterns, and a hyper-adaptive food chain. - Visual Style: Alien jungles with bioluminescent canopies, bone-dry canyons filled with toxic fog, oceans of liquid methane, and insect-like hives built into natural rock formations. - Tone: Gritty, realistic survival. The planet is indifferent to human presence. There are no ancient ruins, no intelligent species—only an ecosystem that reacts aggressively to intruders. - Creatures: Entirely original fauna. Predators are designed based on real-world extreme survival adaptations (camouflage, ambush predators, swarm tactics). Avoid humanoid enemies. Emphasize *alien biology* (multi-limbed, eyeless, hive-mind behaviors, etc.). - Environmental Threats: Acid rain, magnetic storms, tectonic shifts, suffocating fungal spores, parasites. The environment itself is an active threat. - Story Loop: Players must scavenge shipwreck debris, build makeshift shelters, craft survival tools, and explore for essential resources (water, breathable air, power cells). - Escalation: As players venture further, the ecosystem reacts to them. Predators track them across distances, migration patterns are disrupted, and their mere presence causes ecological ripples. - Opening Scene: Players regain consciousness in the wreckage, alarms blaring. Hull breaches expose them to a toxic atmosphere. Supplies are minimal, and night is approaching fast. - Dialogue Tone: Tense, minimalistic, survival-focused. The ship’s AI may be fragmented or offline. Communication is through raw data feeds or glitchy interfaces. - Thematic Focus: Isolation, resourcefulness, and the overwhelming indifference of nature.

Hive Scream

If the swarm is not dealt with quickly, it emits a piercing scream that calls 1d4 additional Razorwing Swarms to join the battle within 1 minute.

Swarm Cloud

The swarm obscures vision in a 10-foot radius and causes continuous bleeding wounds, dealing 2d4 slashing damage at the start of each target's turn.
