Based on the famous German science-fiction literary series "Perry Rhodan". From the back of the box (translated): In this game, the players are piloting a space ship with a set amount of fuel. Pirates will force them into unforeseen maneuvers, so they have to keep track of their fuel supplies. In many different scenarios up to four players may engage at the same time, while the rules are different each time. The basic rules, though, stay the same in every game, e.g. for flight maneuvers or movement. In the starting scenarios, they have to deal with navigation and movement, whereas the advanced setting allows for more variation, like different planets, refueling, evasion, freight, etc. The different game phases are navagation, movement, and supply. Then there are expert scenarios, which add mines and rockets to the battles. Here we have these game phases: navigation, ranged weapons, movement, fights, and supply.
