01 / THE PREMISE

Not chosen. Not trained since childhood. Not ready.

You are not an astronaut.
You are a customer.

You signed the waivers. You passed three days of training. You felt the engines light beneath you. Eight minutes later, Earth is falling away—and the hull makes a sound no engineer put in the briefing.

Civilian passengers approach a rocket at a stormy coastal launch complex

ACT I · QUALIFY

Earn your seat.

Train the body you actually brought. Fitness, nutrition and G-tolerance are earned through action—and the launch remembers every shortcut.

A passenger turns toward three unexplained marks in the spacecraft hull

ACT II · LAUNCH

Feel every decision.

You are crew, not cargo. Run checks. Brace. Acknowledge commands. When the warning lights change, what you did on Earth changes what happens in orbit.

A duty officer works through a systems failure inside a Mars surface station

ACT III · SURVIVE THE ROUTINE

Own the consequences.

On Mars, heroics are paperwork done too late. Triage failing systems, exhausted people and delayed orders from Earth. Every failure traces back to a choice.

02 / HOW IT PLAYS

Tension without a trigger.

Mars Fever treats procedure, people and accountability as the action.

PHYSICAL PROCEDURE

Do the work.

Close the valve. Check the gauge. Sign the log. Correct order matters, and skipped verification comes back later.

HONEST SYSTEMS

Understand the machine.

Water, power, air and bodies are connected. Nothing fails because a random number decided it would.

HUMAN CONSEQUENCES

Carry the people.

Six crew members have needs, history and opinions. The station survives only if they do.
