About the adventure
Your free trader — think Serenity or the Millennium Falcon — has just broadcast the most famous distress call in Charted Space: “Mayday! Mayday! This is Free Trader Beowulf…” Seconds later, Vargr corsairs smash their way aboard. Explosions rock the deck. The lights flicker out. Your ship is no longer home — it’s a battlefield. This one-shot drops you into the middle of a desperate boarding action. You’ll make split-second choices as you battle snarling Vargr in zero-G corridors, fight to keep your vacc suit sealed, and reroute life support before the Beowulf becomes a coffin. Every roll of the dice may spark a new malfunction. Systems fail. Gravity fluctuates. Panic rises. Expect gritty, close-quarters cinematic sci-fi action. Combat is fast, tactical, and personal — grapples, parries, and armor matter — but so does your nerve. Stress and panic mount with every wound, forcing you to push your character to the limit. If you love the feel of Aliens or The Expanse, this game is for you. No prior Traveller experience is needed — we’ll create characters together at kickoff with an easy online tool. All you need is a mic, a little courage, and the will to fight for the Beowulf.

What Greg brings to the table
I run tense, cinematic sci-fi where the ship fights you as much as the enemy. My focus is immersion, fast-moving combat, and keeping you on the edge of your seat. Expect battles that feel brutal and personal — where grapples, parries, and armor make the difference between surviving another round or watching your suit tear open in vacuum. I’ll describe the chaos around you so you can feel the Beowulf groan and fail under the Vargr assault. The game is tactical, but never bogged down. I use streamlined tools to keep rolls quick and the action flowing, so we stay in the moment. When you make a desperate move, I’ll lean into the Rule of Cool — rewarding creativity when it heightens the drama. Above all, I want you to feel the pressure: the stress creeping in, the panic threatening to overwhelm, the victory of holding the line when everything is stacked against you. If you want a GM who pushes you into hard choices, paints vivid sci-fi chaos, and makes every roll matter — that’s what I bring to the table.
Homebrew rules
The Beowulf isn’t just a backdrop — it’s an active, hostile presence in this game. My custom rules turn the ship, your gear, and even your own nerves into part of the fight: Dynamic Ship Malfunctions — Every bad roll can spark a new crisis: power loss, zero-G, failing life support, or sudden darkness. The longer the battle drags on, the worse the Beowulf treats you. Stress & Panic — Wounds don’t just hurt; they rattle your nerves. The more you bleed, the closer you edge toward panic in combat. Stimstix Reliance — Quick fixes exist, but they come at a cost. Popping a stim can keep you fighting — or push your stress past the breaking point. Fast, Gritty Combat — Grapples, parries, and armor aren’t optional fluff; they’re the difference between survival and a vacuum-sealed grave. My streamlined macros keep the action moving. Suit Failures — Even your vacc suit isn’t safe. Under pressure, seals rip, visors crack, and oxygen runs thin. Every malfunction is personal. These tweaks make sure the fight isn’t just against the Vargr — it’s against your own ship, your equipment, and your breaking point.

How Greg creates a safe table
This adventure is intense — close-quarters combat, claustrophobic corridors, and the constant threat of the Beowulf breaking apart under you. But while the story pushes characters to the edge, I always keep the players safe. No gore, no attempt to jump-scare or make the players feel unsafe or uncomfortable IRL. At my table, we use Stoplight Cues (green / yellow / red) via voice and text or X Cards in Roll20. At any point, you can signal for a pause, shift, or stop — no explanation needed. Breaks are always available. After the session, we’ll do a short debrief to cool down and shake off the pressure of the story. My goal: you should feel free to enjoy the panic of your characters, knowing you’ll never be trapped in it yourself.
