Crafting is done either on the fly or at a Bench. While the former is undeniably faster to do, it tacks on an additional 100% component cost to craft anything, and weapons cannot be created/upgraded on the field.
The craftable supplies are divided into three distinct categories: Ammo and Weapons, Warden Bolts and Medical, each having their own set of unique ingredients. An ammo type becomes available to craft as soon as its corresponding weapon is found with the exception of Warden Bolts, which require Sebastian to discover a specific bolt type first before it can be created.
By the time of The Evil Within 2, Green Gel is no longer spent to upgrade weapons. Instead Crafting Parts and their High-grade variants are used. Normal crafting parts are very common later on and are spent in large quantities to upgrade anything, while High-grade parts are spent on unlocking upgrade tiers only.
As weapon upgrading is disabled on Classic difficulty, these will understandably not spawn.
Common crafting supplies are as mundane as their name suggests. These can be found pretty much everywhere, and Safe Houses tend to have some. Some of these components will only spawn once their related craftables have been discovered, most of which are bolt parts.
Specific parts are only used to craft or repair certain items.
- Sniper Rifle Body: Found on the roof of the closest building to the right of the Union Visitor's Center. It is guarded by a single Lost and is found next to a dead MOBIUS soldier with the communicator containing the location of the remaining parts.
- Sniper Rifle Barrel: Found in a shed on the northwestern end of the residential area in the same chapter. It is guarded by a Lament and multiple Losts.
- Flamethrower Body: Retrieved from Liam O'Neal's dead body in Chapter 11. Unmissable.
- Flamethrower Tanks: Found on dead Harbingers in Chapters 13 and 14. Two are needed to repair the Flamethrower, and additional ones can be collected for 99 units of fuel each.
