All Secrets and Purity Seals in Crucible

Secret 1 – Machine Spirit

At the beginning of the level, drop into the lava area and continue through the first metal structure. When you reach the giant cog in the lava, turn right before passing through it. Collect the Machine Spirit hidden in this area.

Remember to equip the weapon you want to upgrade before picking up the Machine Spirit.

Secret 2 – Grenade Boost

Continue through the level until you reach the area filled with metal columns. Look left or right for an open freight container.

Jump inside the container to collect the Grenade Boost.

Secret 3 – Boltgun Magazine

After passing through the area with metal columns and pipes, look for a structure marked with white squares. Instead of continuing forward, go around its left side.

Collect the Boltgun magazine hidden behind the structure.

Secret 4 – Machine Spirit

Continue until you reach the section with metal platforms leading upward. When you reach the platform that touches the cliff, look to your left.

Jump across to the nearby platform to find the fourth Secret, a Machine Spirit.

Secret 5 – Munitions Boost: Lock and Load!

After activating the first switch that raises the lava, continue along the route until you find a blue glowing panel above a platform. Shoot the panel to release the platform, then proceed through the destroyed metal structure.

When you reach the third platform, which slopes slightly upward, turn around and look beneath the platform you just crossed. Carefully drop down to collect the Munitions Boost: Lock and Load!

Secret 6 – Machine Spirit

Continue past the previous Secret until you reach a platform with two metal beams extending upward.

Climb the higher beam to reach the top, where you will find another Machine Spirit. Make sure you have the weapon you want to upgrade equipped before collecting it.

Purity Seal 1

After activating the second switch that raises the lava, follow the narrow path forward. Look up and to your left to spot a Purity Seal resting on a platform suspended from a hook.

Shoot the blue glowing panel above the platform to make it drop. Then use the broken pipes on the left to climb up to the lowered platform and collect the Purity Seal.

You will also receive 50 Boltgun ammunition.

Secret 7 – Machine Spirit

The final Secret is located inside a broken pipe beneath the Purity Seal platform.

Search the pipe you passed while climbing toward the Seal. Collect the Machine Spirit inside to complete the level's Secrets collection.

Final Thoughts

Crucible has seven Secrets and one Purity Seal, with most collectibles hidden away from the main route. Check the sides of structures, explore the platforms around the lava, and shoot blue glowing panels whenever they appear overhead.
