Hecaton Machine Gun evolution recipe

Answer: Requirements to evolve Saber Machine Gun into Hecaton Machine Gun

Weapon level alone is not enough. Trigger Shockwave at least once during the same run.

Steps

1. Obtain Saber Machine Gun and raise it to level 6.
2. Trigger the Shockwave Glimmer with Saber Machine Gun at least once during the same run.
3. Open an eligible chest after every requirement is complete.

If it does not evolve

• Confirm that Saber Machine Gun is level 6.

• Confirm that Shockwave triggered during the same run.
• Open an eligible chest only after every requirement is complete.

For a two-stage evolution chain, the first and second evolution each require a separate eligible chest.
