Where to buy Onyx - Strategy Guide at the best price? As of 24 Aug 2026 this title has one offer, £0.72 at Steam. On PC that is the usual case, because only about one title in four gets a keyshop offer and the rest stay with the platform store. There is nothing to compare, but we track this price daily and show how it stands against earlier readings, and a price alert will tell you about any drop. This is an add-on, so you also need the base game to play it. That costs £0.42 today, which puts the pair at £1.14. On PC you buy a key that you activate in Steam or another client, and this is the widest market we track, with more than a quarter of games carrying a keyshop offer.
