Evolve Boltgun with the Dice Cube passive
In the October demo, Boltgun plus the Dice Cube passive yields Heavy Bolter. Max Boltgun, keep Dice Cube in your loadout and open an eligible boss chest to trigger the evolution.
Dice Cube and D6 Dice are different items: the former is the recipe passive, while the latter is an explosive weapon. If Dice Cube is missing, check its Objective before planning the evolution run. This guide follows the October demo pairing and chest route, with older May-demo information kept separate.
The items in the Heavy Bolter route
| Item | Effect or role | How to get it |
|---|---|---|
| Boltgun | The base weapon fires bursts of explosive bolts in the direction your character faces. At level 8 it fires 6 bolts. | Already unlocked in the demo’s starting weapon pool; acquire it during a run. |
| Dice Cube | The extra-attacks passive paired with Boltgun for Heavy Bolter. | Check its Objective. Demo players report unlocking it by raising D6 Dice to level 6, then receiving it from level-ups in later matches. |
| D6 Dice | An explosive dice weapon used for the reported passive-unlock objective; it does not replace Dice Cube in the recipe. | Unlocked from the start in the demo’s base weapon pool. |
| Heavy Bolter | The evolved weapon delivers sustained, penetrating projectile fire for crowded lanes. | Carry Dice Cube with a max-level Boltgun, then collect an eligible boss chest. |
Make Dice Cube available before chasing the recipe
Check the Dice Cube Objective in the universe you are playing. For the Boltgun route, the October demo report calls for raising the D6 Dice weapon to level 6. Completing that unlock condition gives Dice Cube a chance to appear among level-up choices in later matches.
Treat unlocking the passive and acquiring it in a run as separate jobs. Finishing its Objective does not promise an immediate Dice Cube offer, and carrying D6 Dice alone does not complete the Heavy Bolter pair. Once the passive becomes available, select Dice Cube by its exact name when building around Boltgun.
Turn your Boltgun into Heavy Bolter
- Acquire Boltgun during a run. It is already in the demo’s unlocked weapon pool, so build your level-up choices around upgrading it.
- Take the Dice Cube passive when offered. Check that your loadout contains Dice Cube itself, rather than only the D6 Dice weapon used for its unlock objective.
- Raise Boltgun to level 8, its demo maximum. Keep the passive equipped while you finish the weapon’s upgrades.
- Collect an eligible boss chest after the pair is ready. On Imperial Bastion, target a chest from minute 10 onward, when Evolution appears as the first prize in the demo’s boss chests.
- Check that Heavy Bolter is the result. Its sustained projectile fire is the payoff for completing the Boltgun and Dice Cube combination.
Boltgun bursts versus Heavy Bolter fire
The base Boltgun attacks in bursts of explosive bolts, with its fire following the direction your character faces. Heavy Bolter changes that feel to more sustained, penetrating projectile fire suited to clearing crowded lanes. Plan your movement so the attack has a useful lane through the approaching enemies.
That change in firing behavior is the reason to pursue the evolution. While preparing it, use the base weapon’s facing direction deliberately instead of moving without watching where its bursts go. Keep an escape path available as you line up the next pack.
Dice Cube also serves an Age of Sigmar recipe
| Universe | Base weapon | Passive | Evolution |
|---|---|---|---|
| Warhammer 40,000 | Boltgun | Dice Cube | Heavy Bolter |
| Age of Sigmar | Boltstorm Pistol | Dice Cube | Typhoon Crossbow |
The shared passive does not make these the same weapon route. In the October demo, Boltstorm Pistol uses Dice Cube to become Typhoon Crossbow, while Boltgun uses it to become Heavy Bolter. The May demo list paired Boltstorm Pistol with Lightning Bolt, so use the pairing that matches your demo.
The unlock check also differs by universe in the player report. It lists D6 Dice at level 6 for the Boltgun side and holding four weapons simultaneously for Age of Sigmar. Read the Objective in the universe you intend to play before spending a run on the other condition.
Have the pair but no evolution?
Check availability, equipment and the chest step in that order. If Dice Cube has never appeared, inspect the Objective; if it is available, make sure you actually selected the passive in this run. Then check that Boltgun has reached its maximum before collecting an eligible boss chest.
Simply owning both base items is not the whole evolution sequence. The demo player’s route calls for a maxed weapon followed by a boss chest, so a newly acquired Boltgun still needs upgrading. Use these as October-demo instructions when comparing your attempt with an older May guide or a full-release build.
