An architecturally basic but action-packed (not so) short single player campaign for Unreal.
-Short version: Your ship got attacked and you need to get off, but when
you land on a friendly planet you find more Skaarj and say “Damn.”
-Long Version: You are a fairly new yet skilled member of the UDI
(Universal Defense Initiative), which is responsable for protection of
the human race and its allies from the Skaarj and other hostile races. You
are on a small IRDC “special purpose” (while it seems to you that it serves
no purpose, considering it has such weak defenses and doesn’t even have a
valuable cargo) shuttle called the Renegade. You are returning to Earth after
patrolling an area near a planet far from Earth called Tropherous. Tropherous was
colonized about 30-40 years ago as a large mining operation. Little do you
know that the Skaarj know something about the planet that the colonists and
miners don’t know. What they know is so great that they began a full-scale
invasion of the planet. When your small, nearly defenseless ship is sighted,
they immediately fear that you are a spy and aim to take you out. And so the
ship is attacked.
The Skaarj have damaged many parts of the ship and the main power source
is destroyed. The door leading to the hangar has been blocked, and the
Emergency Teleporters that lead to the hangar are offline due to the power
drop. Engineering is locked and the coolant system is damaged, so the engines
are overheating and will soon detonate the whole ship.
Your only hope is to activate the EPS (Emergency Power System) to unlock
Engineering and restore power to some parts of the ship. In the Engineering
section, you can try to divert the engine power to lower the core temperature
and to aid the EPS, which will also activate and unlock the
Emergency Teleporters. Miraculously, the escape shuttle in the hangar is
undamaged. Get to the shuttle and get off the ship as fast as possible.
