Activator Pen elsewhere in the Annex, return to the crate, and use the panel to claim the muzzle attachment for the Equalizer Mk. II. Open it before leaving the chapter area; guides warn the location may not be revisitable.
Where is Voss’s Compensator?
Look for the first Emergency Relief Crate (E.R.C. crate) on the first floor of the Library Annex, in the area guides variously call the Registry or Reception. It appears during Chapter 2, “The Wake-Up Call.” The room names differ between guides, but they refer to the first Annex crate. VGTimes’ upgrade guide identifies the chapter, while AllThingsHow’s crate guide lists it as crate #1 on the Annex’s first floor.

How to unlock the crate
- Find the crate and note its location. It is locked when you first encounter it; seeing it does not automatically unlock it.
- Explore the Library Annex for an E.R.C. Activator Pen. This key item is found elsewhere in the Annex.
- Return to the Registry/Reception crate. Use the Safe Room or an opened shortcut to retrace your route if available, and deal with any enemies in your way.
- Interact with the crate’s panel using the Activator Pen. Open the crate and collect Voss’s Compensator.
- Equip it on the Equalizer Mk. II pistol if you want to use the muzzle attachment.
The crate and pen are separate steps: picking up the pen does not open the crate automatically. You must return and activate its panel, as described by NerdsChalk and VGTimes. Exact route order can vary with your progress through the level.
What does Voss’s Compensator do?
It is a weighted muzzle attachment for the Equalizer Mk. II. VGTimes describes it as helping you aim more accurately under pressure. The available guides do not provide a numerical accuracy, recoil, spread, or damage modifier, so there is no verified percentage to cite.
GamesRecon’s Library Annex walkthrough also reports that fully focused shots can slow enemies. That effect is not corroborated by the other guides cited here, so treat it as unconfirmed rather than a guaranteed property of the attachment.

Yes. Guides caution that the Annex area may not be revisitable after you progress beyond the chapter area. Because the crate requires finding the pen and backtracking, make sure you complete both steps and loot it before moving on. The sources describe it as potentially missable rather than establishing that every route or game version makes it permanently missable.
