You have 90 parsecs left of your journey back home-planet. Suddenly the alarms blast off and lasers fill up the space around your ship. Control emergency droids to repair critical systems on-board, seal the hull breaches and generally try to survive!
Uups, the Ship's about to get destroyed! Damn, only 14 PARSECS left...
Of course the distance to the base doesn't matter if your Ship's Warp Engines are no more...
