Warhammer 40,000: Boltgun Tips - Weapons, Movement, and Secrets

Warhammer 40,000: Boltgun is a fast, violent first-person shooter about pushing through big combat spaces as a Space Marine with a heavy arsenal. This tips guide is scoped to the base Boltgun campaign. Forges of Corruption adds its own chapter, enemies, and weapons, so treat that DLC as separate when planning routes or loadouts.

Content warning: Boltgun is built around mature sci-fi combat, blood, gore, and horror-themed Chaos enemies. The advice below stays focused on play, routing, and combat habits.

The campaign is approachable if you keep moving, but it becomes much smoother when you understand how levels, weapon carryover, secrets, and temporary upgrades fit together. Think like a retro-shooter player: clear space, change weapons often, and learn the room before trying to brute-force it.

Essential Tips

1. Keep Moving Through Every Fight

Boltgun rewards motion. Strafe, jump, charge, and reposition instead of trading shots from one doorway. Your Space Marine is heavily armed, but standing still lets projectile fire, melee pressure, and crowding turn a manageable arena into a trap.

Use wide loops around combat spaces. When enemies flood the floor, move through open lanes, thin the nearest threats, then swing back for ammo or health after the pressure drops. If you are losing track of the fight, reset to a wall or corner where fewer angles can hit you.

2. Match Weapons to Enemy Pressure

Do not treat the Boltgun as the only answer just because it is the title weapon. The base arsenal includes close-range, heavy, explosive, and special weapons, and the game expects you to swap when enemy type or distance changes.

Use basic firepower for lighter enemies when the arena is under control. Save heavier shots, special ammunition, and grenade pressure for durable targets, crowded chokepoints, and boss-style moments. Chapter boundaries matter because most weapons need to be reacquired after a new chapter begins, so spend rare ammo with the next few rooms in mind.

3. Use the Chainsword as a Tool, Not a Panic Button

The chainsword is useful for aggression, cleanup, and closing on isolated enemies, but it should not replace spatial awareness. Charge in when you know where the nearby threats are and have an exit path. If you dive into a crowd without a way out, melee range turns into punishment quickly.

Think of melee as part of your movement kit. It helps finish a target, reposition into a safer lane, or remove one enemy that is blocking your path.

4. Choose Machine Spirit Pickups Deliberately

Machine Spirit pickups upgrade the weapon you have equipped when you collect them, and that boost lasts for the level. Before stepping onto one, pause for a second and equip the weapon you actually want improved.

This is especially important when you are carrying several weapons. An accidental pickup on the wrong slot can waste one of the level’s biggest power spikes. If the next arena looks cramped, favor a weapon you can use safely under pressure. If you expect tougher targets, choose something that helps burn them down.

5. Replay Levels for Missed Secrets

Completed levels can be replayed, so do not let secret hunting destroy the pace of your first clear. If you spot an obvious side path, take it. If searching every wall makes you lose health or momentum, mark the area mentally and come back later.

Replay is also useful after you learn the chapter’s weapon rhythm. A secret that felt risky on the first pass may be easy once you know where enemies spawn and where the level exit sits.

6. Use Navigation Help When You Are Truly Lost

Boltgun’s levels can sprawl, and some later installs include a navigation aid that points toward the next objective. Use it when you have fully cleared an area and cannot find the exit path. It is better to recover your direction than wander until you burn resources on avoidable mistakes.

Do not follow the path blindly during active combat. Clear immediate threats first, reload, and then use direction help to move on.

7. Learn Your Input Setup Early

Weapon swapping, grenade use, charge, melee, quicksave, quickload, and navigation commands are all part of playing cleanly. On PC, spend time with weapon slots instead of relying only on cycling. On controller, get comfortable opening the weapon select quickly.

Controls can be changed in the options menu, so adjust anything that slows down reactions. A layout that makes charge, melee, and weapon swap easy will help more than a perfect sensitivity number.

8. Treat Horde Mode as Separate Practice

If your version includes the later free Horde mode, use it as combat practice, not as a replacement for campaign learning. Horde mode is framed around surviving waves. The campaign is still about moving through levels, finding exits, managing chapter weapon resets, and cleaning up secrets.

Skills transfer between modes, but routing habits differ. Campaign play asks you to advance; Horde mode asks you to survive.

Campaign Flow

The base story is linear and split into three chapters. Each chapter contains a set of levels, and every level ultimately asks you to reach the exit. That sounds simple, but the route is often wrapped around arenas, side rooms, secrets, lifts, and locked progression spaces.

When you enter a new level, identify three things: the main combat lane, the likely side paths, and the safest retreat space. Clear forward, but glance for pickups before crossing major thresholds. Retro-style shooters often reward players who check corners and ledges without spending ten minutes tapping every wall.

At chapter transitions, expect your toolkit to narrow. The Boltgun stays with you, while other weapons need to be found again. That makes early chapter fights a good time to lean on fundamentals: movement, basic target priority, melee cleanup, and careful grenade use.

Weapons and Upgrades

Good Boltgun play is not just accuracy. It is choosing the right amount of force. Light enemies are best handled with efficient shots and movement. Heavier enemies deserve stronger weapons, explosives, or a temporary upgrade if one is available.

When you find a new weapon, test its role before hoarding it forever. Ask whether it solves close range, crowds, armored targets, or distant threats. Then keep enough ammunition for the moments that match that role.

Machine Spirit pickups deserve special attention because they upgrade the equipped weapon for the level. Look at the arena, choose the weapon, then collect the pickup. Do not sprint through it during cleanup with a random slot active.

Grenades are easy to forget because the guns are loud and satisfying. Use them to break packed groups, punish chokepoints, or buy space when a charge lane is blocked.

Movement and Survival

Survival starts before you take damage. Keep sightlines short when entering a new room, and avoid standing in the center until you know where the threats are. Once combat starts, move with purpose rather than bouncing randomly. A clean loop through health, ammo, and cover is stronger than frantic strafing.

Charging is powerful because it changes spacing quickly. Use it to escape pressure, close on a vulnerable target, or cross a dangerous gap. Do not spend it just because it is ready. If you charge into unknown space, you may land in the worst part of the arena.

Quicksave and quickload support careful play where available. Save before risky exploration, big fights, or suspicious doors. That keeps experimentation fun instead of turning every mistake into a long repeat.

Common Mistakes to Avoid

1. Do not stand still in arenas - keep moving so enemy fire and melee pressure cannot surround you.
2. Do not spend heavy ammunition on every weak target - save stronger shots for durable enemies and crowded threats.
3. Do not collect a Machine Spirit with the wrong weapon equipped - choose the weapon you want upgraded before stepping onto it.
4. Do not ignore chapter weapon resets - plan around reacquiring most weapons after a new chapter begins.
5. Do not chase every secret during a dangerous first clear - finish the level, then replay for safer cleanup.
6. Do not follow navigation help during active combat - clear the room before using it to find the next path.
7. Do not leave controls at defaults if swapping feels slow - adjust bindings so charge, melee, grenades, and weapon selection are comfortable.
8. Do not mix DLC assumptions into the base campaign - keep Forges of Corruption enemies and weapons separate when planning.
