'Alien 4 - Lithios' is a tactical board game for 3 to 6 players. The playing time is 25 - 30 minutes.
The unmanned spaceship Lithios - loaded with the precious metal lithium - is on its way to Earth. On the way, the spaceship is attacked by Aliens, who want to rob the spaceship of its precious cargo. The cargo is secured by moving parts of the board, which allow corridors to be closed and opened. Only the players who can solve the puzzle of closed corridors and open passages can reach the precious cargo. The players can temporarily eliminate each other in a duel with the so-called duel stones.
