Armed with advanced technology and cutting-edge weapons, you’ll fight against hostile lifeforms that tolerate no other species. Survive the cosmic pressure, land in the Tertaris Mountains, and engage in an epic fight against the parasites.

The parasites are attempting to invade Mars. It’s up to you to stop them and save the future of the Red Planet! Fulfill the Tretrais mission and become a hero of Mars.

Explore the secret hideouts of the parasites in the Tertaris Mountains and plan strategic attacks. Remember, humanity needs you. These mountains are a vital resource for human survival. Only you can put an end to this chaos.

Join your friends on the Tretrais mission and work together to stop the parasites! Who says a mission like this has to be solitary? Collaborate to make the battle even more thrilling and fun.

Mars is an unforgiving environment: oxygen is limited. Refill your supply before it runs out. Gather materials from defeated parasites to craft weapons and defend yourself. Prepare for nightfall—darkness makes everything more dangerous.

Parasites attack both from a distance and up close! Deploy automated turrets to fend off enemies from afar. Be cautious: close-range attacks can deal significant damage.
