'Alien 5 - Nitrogen' is a puzzle and tactical board game for 2 - 6 players. The playing time is 30 minutes.
An abandoned and rusty spaceship floats aimlessly in space. A group of Aliens wants to occupy the spaceship and take it to their home base. The competing Aliens do everything they can to penetrate the spaceship and fly away first. The Aliens even go so far as to (temporarily) eliminate each other. They also have to solve a problem: the spaceship is leaking and the Aliens need nitrogen for their breathing. That is why they first have to collect nitrogen bottles, space helmets and nitrogen hoses and connect them to each other in order to be able to breathe, so that they can reach their goal. The Alien who reaches the command room and makes the spaceship controllable is the winner of the game.
