About This Game

🧟 TRIMSON

TRIMSON is a system-driven zombie survival game where you deploy into infected zones, rescue survivors, gather critical resources, and return home to a settlement shaped by your actions.

Every deployment carries risk. Injuries and infections follow you home. Survivors can be lost. Resources are limited. The people you save can unlock new opportunities for your settlement—and the people you leave behind may be gone forever.

The world remembers what you do.

🚁 Deploy. Survive. Return.

Leave the safety of Trimson and enter dangerous towns, forests, facilities, and abandoned locations in search of survivors and supplies.

Once deployed, there is no simply returning home when things go wrong. Complete your objective, adapt to what happens in the field, and make it back alive.

🧍 Rescue Survivors

Every survivor matters.

The people you rescue become part of Trimson. Survivors can unlock vendors, missions, activities, and new opportunities while civilians react to the outcome of your deployments.

Who you save—and who you fail to save—becomes part of your playthrough.

🩸 Survive More Than the Infected

Combat is only one part of survival.

Bleeding, infection, poison, disease, and other status effects can turn a successful mission into a fight to stay alive. Search for medical supplies, plants, and resources before your condition becomes fatal.

And the infected aren't the only danger outside the walls. Wildlife inhabits the world too, and sometimes avoiding a fight is the smartest decision.

🧟 Face an Evolving Infection

Not every infected behaves the same.

Encounter increasingly dangerous mutations that can chase, overwhelm, ambush, strengthen other infected, and change the battlefield around you.

Learn what you're facing, decide when fighting is worth the risk, and prepare for threats far beyond the common infected.

🏚️ Build a Stronger Trimson

Your progress doesn't end when the mission does.

Gather resources, earn experience, improve your character, discover equipment, complete achievements, and bring survivors home to expand what's available inside Trimson.

Your settlement is more than a menu between missions—it's the community you're fighting to keep alive.

📖 Discover What Happened

Explore the world and recover hidden lore documenting the events that led to the outbreak.

Piece together the experiments, infections, people, and decisions behind the fall of the original Trimson—and uncover the truth behind what now stalks its ruins.

⚔️ Survive Horde Mode

Want to forget the rescue mission and just survive?

Take on increasingly dangerous waves of infected in Horde Mode. Kill enemies, earn currency, purchase equipment, manage your resources, and see how long you can survive as the pressure increases.
