Iron Blight Weapon Attachment Location Checklist

The Iron Blight attachment checklist has 12 documented pickups across six weapons, including the OTs-48K Suppressor in Block A, apartment A.99. Look inside its bookcase, between the books. The table combines room landmarks with video checkpoints so you can search the level without estimating a speedrun's elapsed time.

To install a part, open the matching weapon's interface and click its green attachment dot. The developer's reply confirms that a dot turns gray when the compatible part is absent from carried inventory. Check the full weapon name: two items called Laser Sight are not automatically interchangeable.

The room landmarks come from Danyuv's community walkthrough. Times refer to the separate August 26, 2026 recording by Kane Wheelan & Son, whose installed build is unspecified. The OTs-48K Suppressor has no confirmed chapter timestamp in that recording; A.99 is an apartment detour, not an extra pickup after the ending. This is a documented checklist, not a claim that a latest-build exhaustive collection test has been completed.

OTs-48K Suppressor: A.99 bookcase

In residential Block A, search apartment A.99 before finishing the crossing to Block B. Check the bookcase shelves: the reference shows a dark cylinder between a stack of books and an upright red book. Its on-screen Russian label reads ОЦ-48К ГЛУШИТЕЛЬ, identifying the OTs-48K Suppressor rather than the later SR-3M part.

The paired map image shows floor 15 and a red player arrow in the room on the right of the floor plan. Use it together with the walkthrough's A.99 label; the pickup image alone does not show a room number. If your map labels differ, compare the building, floor and bookcase before crossing to another block.

Collect apartment parts without losing the route keys

The mandatory crossing uses the four apartment dials and A.96/B.95 keys. The optional attachment stops are different rooms:

• A.96: take the connector key by the Gnom and check the table for the RMB-93 Laser Sight.
• A.99: search the bookcase for the OTs-48K Suppressor.
• B.104 and B.101: collect the Gnom Muzzle Brake and Laser Sight respectively.

Take the route key first if space is tight. The Large Backpack checkpoint is in this broader apartment section; reorganize before the factory starts adding the Punch Card and Blowtorch.

Factory, Workshops and Police Station sweep

At the factory, check the box for the Kedr Extended Mag before leaving the Punch Card route. In Workshops, check both the washing machine for the SR-3M Suppressor and the workbench for the RMB-93 Extended Barrel. Keeping these landmarks separate avoids searching the same container for two different parts.

For the SR-3M Scope / PNV, search the Police Station's upstairs filing cabinets. The mandatory Boat Key is in the basement's leftmost cell, so a story run and an attachment sweep have different destinations inside the station. Finish the upstairs collection before committing to the boat return.

Attachment dot is gray or the part will not install

1. Read the complete item name and select the matching gun.
2. Put the loose part in carried inventory if it is currently stored.
3. Open the weapon screen and click the compatible green dot.
4. Check whether the slot is already occupied before searching for another copy.

If the correct carried item still fails, record the weapon screen and item name, restart the current build, and verify files through Steam. Use the inventory guide for capacity planning and the weapon locations if you have the modification before its gun.

Evidence and review

Reviewed October 19, 2026. The previous 11-item list omitted the OTs-48K Suppressor; the original pickup label and paired map support adding it. The table is this wiki's synthesis of room landmarks, weapon compatibility and older video checkpoints. Screenshots retain their original community capture and attribution. No current-build playthrough or achievement unlock was tested by the wiki.
