Notrium is a top-down survival action game. You have crash-landed on planet Notrium. Your food supplies are running low, a pack of predatory aliens have got your scent. There are no more bullets for your pistol, your only weapon a handful of rocks. The night is coming, and you are desperately looking for wood to make a fire. Notrium is a game of survival.

You can play as four different races (Human, Alien, Android and Psionic) that all have varying characteristics.

An integral part of the game is finding enough food and supplies to survive through the cold, dark nights.

Exploring the alien ruins and bases you can find various items, which can be combined to make weapons and equipment.

Most of Notrium's inhabitants are not happy to see you. You can try getting past your enemies quietly, but often you will need either fast legs or a sharp aim.
