Twilight: 2000, in Free League’s 4th edition, drops you into the muddy, radioactive aftermath of a war that never quite ended. It uses a variant of the Year Zero Engine built around step dice — dice of different sizes — so the better you are at something, the bigger the die you throw. Survival, ammunition and injury are all baked into the roll.
The dice and the core mechanic
Instead of a big pool of identical dice, Twilight: 2000 rates your abilities as die sizes from d6 up to d12. Attributes and skills each have a rating that corresponds to a die: a weak rating is a small die (d6), an excellent one a large die (d12), with d8 and d10 in between. When you attempt a task you normally roll two dice together — the relevant attribute die and the relevant skill die.
You then read the dice for successes. A 6 or higher on either die counts as a success, and a single success is usually enough to accomplish the task — extra successes make the result better, faster or more damaging. Larger dice help in two ways: they are more likely to roll a 6, and on a d10 or d12 a result of 10 or more counts as an extra success on its own, so the biggest dice can land two successes from one die. Rolling only untrained means throwing a smaller base die, so competence is felt directly in the size of the handful.
Ammunition and hit location
Combat adds two of the system’s signature dice. When you fire a burst or spray of rounds you roll ammo dice alongside your attack — these represent the rounds spent. Sixes on ammo dice can add to your effect, while low results eat into your dwindling supply, so every automatic burst is a gamble between hitting hard and running dry. Because bullets are precious in a collapsed world, the ammo dice keep the fiction honest: you are always counting rounds.
When a hit lands, a hit-location roll determines where the damage strikes — limbs, torso or worse — which shapes how dangerous the wound is. Injuries in Twilight: 2000 are gritty and consequential, so where you are hit can matter as much as how hard.
How a roll resolves
To make a roll: identify the attribute and skill involved, pick up those two dice, add any dice granted by gear or circumstances, and throw them all together. Count every 6 or higher as a success (remembering that 10+ on a big die is worth an extra). One success clears most tasks; multiple successes let you push for something better. In a fight you resolve your attack the same way, then roll ammo dice for rounds expended and a hit-location die to see where a wound falls. Failure, injury, radiation, thirst and exhaustion all press in from the edges — the dice are only one of the pressures the game keeps on you.
Effective strategy
- Chase bigger dice, not more of them. Because this is step-die, raising a skill from d8 to d10 improves both your hit chance and your access to those 10+ extra successes. Investment in your core skills pays double.
- Specialise, then lean on it. Your best results come from pairing a strong attribute with a strong skill. Build a character who is genuinely excellent at a handful of things rather than mediocre at everything.
- Respect the ammo dice. Full-auto fire buys extra effect but burns your irreplaceable stockpile. Save the long bursts for moments that truly warrant them, and favour aimed, single shots when you can afford patience.
- Play the survival layer, not just the fight. Food, fuel, shelter and medical care decide campaigns here. Winning a firefight means little if you bleed out or starve afterwards, so treat logistics as seriously as combat.
- Use the terrain and the clock. Cover, range and preparation all tilt the odds. A prepared ambush from concealment is worth far more than a heroic charge into open ground.
Beginner tips and common mistakes
- Count successes, don’t total the dice. You are looking for 6s, not the sum of the two dice. One success is usually plenty.
- Remember the 10+ bonus. New players often forget that a big die showing 10 or more is worth an extra success — a real reward for high ratings.
- Don’t treat ammo as free. Every burst you roll can deplete rounds you cannot easily replace. Track your magazines as carefully as your health.
- Wounds are serious. This is not a game of soaking damage endlessly. Avoiding hits, using cover and treating injuries quickly all matter more than raw firepower.
- Encumbrance and supplies bite. Carrying too much slows you down and running out of essentials ends characters. Plan what you haul and where you will resupply.
