A Sci-Fi Gun Powder Plot Scenario

 Down The Hatch Or Maybe An Exhaust Vent...

You and your crew have been contracted to take out a rival gangster boss and you have intel he will be on his orbital space station for a big party on November the 5th.

All the rival gangsters will be there, so this could be a really sweet pay day so long as you are morally ambiguous towards mass murder of strangers that is...

You will need to find a way to infiltrate the space station - maybe you could go dressed up as old washerwomen, or maybe that wont wash, maybe as strippers, or maybe as a minor boss man and his crew with fake invites if you can hack someone else with an invite. Maybe space walk over and try to access via a waste vent, or a little used airlock into the docks and cargo bays.

For this scenario set up a number of ways that your crew could access the space station and then test according to your preferred set of rules how your crew gets on and use any abilities your crew may have to your advantage. 

Allow the crew to attempt access three times but each one that is failed cannot be re-attempted i.e. you can't attempt to acess the space station the same way twice.

If your crew fails all three times - get a new crew! They've been detected and killed.

Once in, you will need to stealth your way through the spcae station to an exhaust vent, down which you put a smart explosives package that can be remote detonated. You then need to get off the space station without raising the alarm and detonate the explosives remotely. 

Stealth, hacking, and silent killing abilities are key. 

The game board should obviously consist of corridors, the crew navigating from one end to the other of the board, undetected, or killing as quietly as possible as they go. They may need to ascend or descend some floors to get to the exhaust vent - there is only one of these that they can use. 

You may need to do a sketch map of the access points the crew could potentially use and their position in relation to the exhaust vent they need to get to. Obviously the access points nearest the exhaust vent should be the hardest to access. 

There should also be guards and security patrols along all, or most, of the corridors. You an do a bit of RPG here if you so wish.

Once the explosive is deployed, the crew will have to leave the same way they came, even if the initial guards and security patrols have all been eliminated, the GM should dice for random patrols turning up as the crew progresses. 

In terms of rules to use, if you are looking for recommendations, then Starport Scum, Five Parsecs From Home, and Space Weirdos will all serve well.

I know what you are asking, if its an exhaust vent then surely it can be accessed from the outside of the space station? Nope! Why? Because the external vent is heavily watched, guarded, and defended - lessons have been learnt. The only way to do this is to access the exhaust vent after the point in the vent where security measures are still in effect i.e. deep in the space station itself. 

Why not just go to the engine/generator/reactor area - again this is heavily watched, guarded, and defended. This is your only shot. 

If the crew are successful and blow the orbital space station up, the subsequent fiery display in the nights sky, seen from the surface of the planet below makes for a wonderful spectacle.
