Only for DOOM: The Dark Ages owners who want a blacked-out Slayer; adds nothing playable.
Compare Prices(1 stores)
Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About Doom: The Dark Ages - Onyx Slayer Skin (DLC)
The friction here hits before you even load in: this is a Bethesda.net redemption code, not a Steam key, so you make an account, log in, punch the code into your profile page, and hope the entitlement shows up on the platform you actually play on. That is the whole first-hour hurdle, and it is worth pushing through only if you already own DOOM: The Dark Ages, because the Onyx Slayer Skin does nothing on its own. It is a cosmetic add-on that requires the base game to work. What you get is an alternate black armor set for the Slayer, applied in the campaign's skin selection. No missions, no weapons, no shield saw variants, no stat changes. Check the store listing for the exact item breakdown, since the pack is thin enough that the name covers most of it. For completionists building out the full cosmetic roster, or anyone who thinks the default Slayer looks too bright against all that medieval gloom, fine. Everyone else can walk past.
