About This Game

🚀 Welcome to Tretrais: The Battle for Survival on Mars Begins! Tretrais is an action-packed survival and base-building game set on the surface of Mars in a distant future. After your spaceship crashes due to a malfunction, you are the only survivor. You must build a base to sustain life in harsh conditions and fend off enemy waves that begin every night at 9:00 PM.

🛸 Enemy Variety Each night’s attacks will challenge you not only in numbers but in diversity. From leaping creatures to explosive enemies, ranged attackers to heavily armored beasts — each enemy type demands different strategies and defensive setups.

🔫 Weapons and Upgrade Systems Tretrais starts you off with four main weapons that automatically target the nearest enemy. But shooting alone won’t save you. You can upgrade your weapons to improve damage, range, fire rate, and add special effects like burning, freezing, or electrifying. Choose combinations that match your strategy!

🧠 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!

🗺️ Explorable Map and Hidden Areas Survival is only part of the mission — exploration awaits! Discover new areas, collect resources, investigate abandoned structures, and follow mysterious signals to unlock surprise quests. Beneath the red surface of Mars, remnants of the past are waiting to be found.

🤝 Co-op Mode: Survive Together Not a fan of going solo? Good news! Tretrais supports online co-op mode, so you can team up with friends. Build your base together, share resources, and fight off enemy waves side by side. Strategic teamwork becomes crucial as the days go on.

Are You Ready? You’re alone on Mars — but not helpless. Rise from the wreckage, build your base, arm yourself, and survive the nightly threats at 9:00 PM! Tretrais will test your reflexes, intelligence, and determination. It’s time to write your own story on the red planet.
