Best Engine Rifle build at a glance
The Engine Rifle is a serviceable starter, not a dead run. Its steady hit rate supports Goldburst and status triggers, but it needs more upgrades to reach the payoff other weapons receive from their defining mechanics.
- Primary fire
- Gatling Fire
- Secondary fire
- Engine Rev
- Aspect
- Goldburst (Fortune)
- Weapon Forge
- Prolonged Revving · Heat Converter · Large Capacity
- Ability
- Frag Grenade
The baseline automatic. It struggles with damage and overheating and its mods do not rescue it — move to another weapon as soon as you unlock one.
Best for: Early game only — swap out once you unlock a weapon
Recommended Engine Rifle build
If you are stuck with it early, its saving grace is the high fire rate: Fortune (Goldburst) turns every shot into gold-scaled damage. If that route is not working for you, select another unlocked weapon at the Lobby Workbench before the next expedition.
Primary and secondary fire
Gatling Fire (Primary) — Increases Fire Rate the longer you shoot.
Engine Rev (Secondary) — High Fire Rate but increases Heat.
Best Aspect and Blessings
Alternatives: Barrier (Defense)
Exact weapon Forge picks
- Prolonged Revving — Shooting enemies reduces Heat.
- Heat Converter — Deal up to 100% more damage the higher your Heat is.
- Large Capacity — Increases the max clip size and the Overheat threshold by 100%.
Ability and Charm slots
Frag Grenade — A thrown explosive for ranged area damage.
One equipped Charm by default. Charm Power unlocks a second slot. The following choices are conditional priorities to find during a run.
- One-slot priority
- Gold Lure
- After Charm Power
- Gold Lure + Golden Ticket
These are early economy priorities for the Goldburst route: seek more Loot Golem opportunities, then preserve gold through cheaper purchases.
When to swap: Replace an economy pick with Giant Slayer before an isolated elite or boss when immediate damage matters more than future purchases. If Gold Lure is locked or not offered, Golden Ticket is the alternative economy pick, not a required companion.
Compare the guide’s candidates: Gold Lure · Golden Ticket · Giant Slayer.
Editorial priorities
These are planning goals, not Ancient Forge item names.

Before you can use this setup
- Gatling Fire: Eco Warfare — Kill 10 enemies without reloading with the Engine Rifle.
- Engine Rev: Available when this weapon is unlocked.
- Frag Grenade: Available from the beginning. Ability unlock details →
- Unlock Ancient Forge to find upgrades during expeditions. The listed upgrades are priorities, not guaranteed drops; Artificer permits a weapon and ability choice at the same Forge.
If a recommended mode is still locked, start with this weapon’s default modes (Automatic Fire / Engine Rev). Treat that as a temporary setup and pursue the listed challenges before expecting the full route.
Charm names link to their effects and challenge unlocks. Unlocking an item adds availability; it does not guarantee it will appear in your next run.
How to make the build work
- Use magazine or heat-management comfort to keep the weapon firing through early rooms.
- Take Goldburst or another repeated-hit payoff rather than building around single-shot criticals.
- Invest only enough to stabilise the run; keep evaluating unlocked replacements at the next opportunity.
Solo, co-op and boss adjustments
Solo route
Use the predictable automatic fire to learn target priority and movement. Stop firing before heat or reload leaves you exposed, then reposition during the downtime.
Co-op role
Apply steady pressure and finish low-health enemies while specialists handle burst windows. Status spread can give the rifle a useful support role in crowded encounters.
Boss plan
Short controlled bursts preserve movement and prevent the weapon from entering downtime during an exposed phase. A damage ability carries more of the single-target burden here.
Common mistakes
- Over-investing after a stronger unlocked weapon appears
- Holding fire until heat or reload overlaps a boss damage window
- Copying a slow-weapon critical build onto an automatic starter
Deep Water 30 variant
Before starting Deep Water 30, check whether Heat downtime is ending your damage windows. Use short bursts and a damage ability; consider another unlocked weapon at the Lobby Workbench if this firing cycle remains unreliable.
