In Space Lifter, you operate a transportation space station. Much like your UPS colleagues down on Earth, you have to pick the cargo from where it was left and deliver it as quickly as possible to its destination. In whole.
Various obstacles of natural and artificial sources are in your way and prevent this job from being completely automated.
The G-force of a nearby planet is pulling the ship down whenever in open space and you must periodically use the engine power to maintain latitude. Left and right ship bumpers help you navigate your way through space.
Other space stations and occasional rockets better be avoided, although they could also be neutralized by using an energy-hungry power shield.
The initial game release features 50 different playing levels of increasing difficulty, plus some bonus levels. More levels can be created with the SpaceLifter Level Editor, which is also included in the trial packages for the game.
