So after promising for my players to do a horror adventure for the past year I've finally gotten around to actually to writing and prepping for it. I'm combining both of my local groups to play this while intertwining plot threads from both campaigns. Both groups share a BBEG and often run into each other.
The plot of this thriller starts with one of the PC's receiving a tip from an old friend where a one night stand turned ISB agent foe is currently infiltrating. This ISB agent is currently within a group (multiple ships)of pirates as they meet to decide whos in charge after the previous guy died (BBEG fault). While the agent isn't BBEG this could give them a lead on the BBEG. The party will be tasked with infiltrating/Assaulting the meeting to interrogate this agent where they will be lured aboard the main pirate capital ship (homebrew design).
It will take off while they will undoubtedly tear through pirates. when in, hyperspace when it is wrenched out of hyperspace because the hyperdrive has been destroyed, the lights go out, and the sounds of screaming and blaster shots will echo throughout the ship. The ISB agent has been instructed to plant bombs in engineering and engine section and been told that after their detonation, reinforcements will capture the disabled craft. However the diabolical BBEG was really using this opportunity to test a variant of a deadly poison gas that who ever inhales it will turn into ravenous mindless Rakghoul.
Basically the plot consist of the team (maybe) teaming up with pirates to repair the communications suit and hyperdrive of the vessel and the back of the ship. They will have to carve through a ship full of Rakghouls (with all sorts of unique variants) to get to it though, in the dark.
My question is that while I want to have some threat of going down from one of the guys mean infection, I dont want a one hit KO sorry role another character moment. I want some parts of the ship more difficult to progress in due to lingering gas and a limited hand held air supply for gas masks, but I dont want a bunch of threat to knock off that mask and kill another character due to the gas. Any advice on how to ramp up the threat but keep the unfairness (gameplay wise) of a Rakghoul outbreak out of the game.
Im homebrewing a lot of the element of a rakghoul btw. And yes I know that I'm ripping off dead in the water.
