Pair Lasgun With Gauntlet
In the October demo, carry Lasgun with the Gauntlet passive, upgrade Lasgun to its maximum, and open an eligible boss chest to evolve it into Meltagun. Recruiting Trooper Bartosz Kozlowski or gaining extra soldiers through Lasgun upgrades is separate from that evolution.
Prepare the Weapon, Passive and Rescue
Gauntlet starts unlocked in the demo, so it is the passive to watch for when assembling this pairing. Kozlowski begins his runs with Lasgun, but rescuing him on Imperial Bastion is a distinct objective that unlocks him as a playable champion. If you prefer to remain with Malum Caedo, choosing Lasgun after the rescue can bring Kozlowski along to fire it instead.
Find the Munitorum Dataslate to open the Armoury for your universe and consult its evolution records. Keep your rescue objective and your equipment choices as separate goals when planning the run. That makes it easier to identify whether you still need access to Kozlowski or simply need to finish the Lasgun recipe.
Set Up the Meltagun Evolution
- Rescue Trooper Bartosz Kozlowski on Imperial Bastion to unlock him as a playable champion. His rescue is found through a question-mark objective, where you must deal with the enemies surrounding him.
- Select Lasgun for your run. Kozlowski starts with it, while Malum Caedo can recruit Kozlowski as a follower by choosing the weapon after completing the rescue.
- Take the Gauntlet passive when it is offered so your run holds the matching companion. This is the passive paired with Lasgun for the Meltagun evolution.
- Upgrade Lasgun to its maximum while keeping Gauntlet equipped. Treat the additional squadmates gained along the way as Lasgun upgrade benefits rather than the completed Meltagun evolution.
- Open an eligible boss chest after preparing the maximum-level Lasgun and Gauntlet pairing. This is the chest step in the October demo's Meltagun route.
Rescuing, Recruiting, Upgrading and Evolving
| Progression | What You Get | How It Happens |
|---|---|---|
| Rescue Kozlowski | Kozlowski becomes a playable champion. | Complete his rescue objective on Imperial Bastion. |
| Recruit Kozlowski as a follower | He follows your champion and fires Lasgun at the nearest enemy. | After rescuing him, choose Lasgun while playing Malum Caedo. |
| Add Cadian Shocktroopers | Additional soldiers support the squad. | Upgrade Kozlowski's Lasgun. |
| Evolve Lasgun into Meltagun | The Lasgun evolution is completed. | Carry Gauntlet, maximise Lasgun and open an eligible boss chest. |
The Keyword system determines who uses an acquired weapon. If your champion's Keywords prevent direct use, a compatible ally can wield it on your behalf, and multiple followers can join the squad. Those followers cannot take damage or collect items, so keep moving your own champion toward safe ground and useful pickups.
Use the Lasgun's Squad Benefits
In the demo, Lasgun adds a follower at levels 2, 4, 6 and 8. Kozlowski gains 5% Veterancy per follower, reaching a 20% bonus from those additions at level 8. Veterancy boosts experience, giving his squad growth a benefit beyond the extra weapons firing around him.
For the full game, the Castellan is another champion to consider alongside Kozlowski: his attack power and skill increase with every follower gained. The additional Cadian Shocktroopers from Lasgun upgrades contribute to that interaction. Keep this announced squad combination in mind when choosing a champion for a follower-focused run.
October Demo Evolution Recipes by Universe
Use the companion column when choosing the rest of your loadout around Lasgun. Each row identifies a base weapon, its matching passive and the resulting evolution in the October demo. Nuln Oil has a shared pairing across both universes, so it appears as a shared entry.
| Base Weapon | Companion Passive | Evolution | Universe |
|---|---|---|---|
| Chainsword | Tape Measure | Eviscerator Chainsword | Warhammer 40,000 |
| Lasgun | Gauntlet | Meltagun | Warhammer 40,000 |
| Boltgun | Dice Cube | Heavy Bolter | Warhammer 40,000 |
| Whirlwind Battery | Liquid Green Stuff | Orbital Bombardment | Warhammer 40,000 |
| Frag Grenade | Bandolier | Ripper Pistol | Warhammer 40,000 |
| Tempest Axes | Sabaton | Whirlwind Axes | Age of Sigmar |
| Nebulous Sea Fog | Bugman's Tankard | Aquatic Illusions | Age of Sigmar |
| Boltstorm Pistol | Dice Cube | Typhoon Crossbow | Age of Sigmar |
| Brazier Staff | Liquid Green Stuff | Master of Runes | Age of Sigmar |
| Rope & Grapnel | White Dwarf | Ghost of Rhea | Age of Sigmar |
| Nuln Oil | Hourglass | Mordant Earth | Both universes |
Check Your Setup if Meltagun Has Not Appeared
- Check that Gauntlet is actually in your current loadout. Having access to a passive and carrying that passive during the run are different checks.
- Check Lasgun's displayed upgrade state. The evolution route calls for the weapon's maximum, so obtaining its base form or adding squadmates does not finish the setup.
- Complete the eligible boss-chest step after preparing the pair. Kozlowski joining your squad is a recruitment result, while Meltagun belongs to the separate evolution recipe.
Keep the Demo Versions Separate
Use this route for the October demo; older May-demo guidance describes a different build. The October pairing is Lasgun plus Gauntlet into Meltagun. Progress from the previous demo does not transfer into the newer demo, and demo progress does not transfer into the full release, so treat this setup as practice for choosing a weapon, its passive and a squad.
