System Upkeep

The entire human race is at risk due to misunderstood negotiations with an alien species. A space shuttle called the MM2002 was hastily constructed, loaded with a 20,000 gigaton bomb and sent to infiltrate the aliens' base of operations. You, together with an almost competent pilot, will go on a dangerous journey through the planet's asteroid belt to launch the bomb. Will you be able to upkeep shoddy space travel equipment and save humanity? Time is limited, and the equipment unreliable.
