Explore the underground alien base and Mars caves
Mars is a much more mysterious planet than meets the eye. Its underworld is riddled with natural caves and tunnelsof a subterranean base.
Once in the secret laboratory, our captured hero managed to deal with the alien and avoid probing. However, this is only the very beginning of his adventures on the Red Planet!
Throughout the game you will have to explore every nook and cranny of the underground base, collect all the alien artifacts, avoid cunning traps and find a way to return home.
Fight against dangerous enemies
Playing Marsmare: Alienation, you will face a variety of enemies.
Among them are:
Martian scientists and military personnel;
Spider robots and drones;

Each enemy requires a special approach: our hero is extremely limited in resources, so one awkward move and you'll have to return to the checkpoint.
Find a way back home
While exploring the alien base, you will discover special items: a blaster, a space suit and a jetpack. Each item will add new abilities and open the way to previously inaccessible areas.
To escape from Mars, you'll need to find the alien flying saucer (yes, yes, the same one on which you were kidnapped!), collect all the energy crystals and fuel.
