Railgun XXVI
Core RulesCore Mechanic
Roll d20 and add one of four stats (STR, CRD, AGI, or MND) against a standard difficulty of 12. Every roll is player-facing: players roll to attack and also roll to dodge incoming attacks, so the GM never needs to roll dice. Rolling a natural 20 banks an adrenaline point, which buys an extra action on top of the two each character gets per turn.
Best For
Groups who want short, lethal firefights on a grid and a GM who narrates enemies rather than rolling for them. Suits a few-session campaign or a drop-in mission night more than a long character-driven arc.
Highlights
Every roll is player-facing, including dodges against incoming attacks, so the GM runs enemies without touching the dice. Dropping to 0 HP forces a critical injury roll that permanently reduces a stat, so downed characters degrade instead of bouncing back up. Several weapons chain into a free attack when they drop an enemy, making target order a tactical decision rather than a formality.
Considerations
Social scenes have no dedicated stat or subsystem, so persuasion is settled by player argument rather than mechanics. Play assumes a gridded map with movement and line of sight measured in squares, leaving theater-of-the-mind groups to convert those rules themselves. Out-of-combat scenes lean on ad hoc GM rulings and a single falling-forward technique rather than a dedicated exploration or investigation subsystem.
