Boltgun evolves into Heavy Bolter with Dice Cube. The inspected release table specifies Boltgun level 8. This is the generic Boltgun chain, separate from Morvenn Vahl's named weapon Fidelis.
Follow the chain
| Check | What you need |
|---|---|
| Base weapon | Boltgun, level 8 |
| Companion | Dice Cube in your inventory |
| Reward | A chest slot that can offer an evolution |
| Result | Heavy Bolter |
The original October demo table names the same companion, while the official survivor reveal names Heavy Bolter as Boltgun's evolved form. Bricky's November 11 launch recording also discusses the Heavy Bolter reward around 55:32 and the pairing screen around 1:19:02; the downloaded automatic transcript is a corroborating reference, not a complete visual audit of every level requirement.
Character and follower context
Brother Luca starts with Boltgun in the developer reveal. Malum Caedo starts with Chainsword, despite being the protagonist of the separate Boltgun games. A weapon's keywords can cause a follower to wield it, as explained in the squad guide.
If you receive another upgrade
Confirm that Dice Cube was selected rather than merely offered, and check Boltgun's own level. Do not swap in Scatter Die because both items mention dice: the passive lookup distinguishes their recipes. An ordinary reward does not prove all future chests are ineligible. This guide does not promise a fixed minute for the evolution.
