A routine mission. One thing goes wrong. Now you're stranded on Mars alone, surrounded, and running out of time. Endless enemies. Limited resources. One escape pod that needs fixing. There's a way out. Mars just doesn't want you to find it.

🚀 Welcome to Tretrais: Mars Was Waiting for You
The near future. A routine transit just a few hours past Mars, nothing unusual. Until your ship starts failing.
You reach the escape pod. It locks onto Mars. The descent begins.
The moment you hit the red dirt, everything changes. Something is wrong with this planet. You can feel it before the dust even settles, before you've taken your first breath. Mars is not silent. Mars has been waiting for you.
The Tretrais Mission begins now.
🛸 No Breaks: A Relentless, Escalating Threat
Enemies don't attack on a schedule they keep coming, and every wave hits harder, arrives faster, and brings something new. Leaping creatures, explosive organisms, long-range attackers, heavily armored heavies each one demands a different response. The longer you hold out, the more Mars pushes back.
🧠 Traps and Turrets
Slow enemies with spike traps and mud pits, blow them apart with explosives, and lock down your perimeter with auto-firing turrets. Every second on Mars counts placement is everything.
🧠 Traps and Turrets to Strengthen Your Defense
When your weapons aren’t enough, traps and turrets come into play. Place spike traps, slowing mud, and explosive mines to halt enemies in their tracks. Surround your base with auto-firing turrets to build a strong defensive perimeter. Smart placement can be a lifesaver!
🗺️ Explore Mars: The Answers Are Out There
Why is this planet like this? What do these creatures want? As you scavenge for parts and push deeper into the map, you'll find that Mars has secrets buried beneath its surface and they've been waiting a long time. Every discovery raises new questions. But your time is running out.
