Where to buy Quantum Conundrum: The Desmond Debacle at the best price? As of 21 Aug 2026 the cheapest option is A$4.50 at Steam, out of 4 offers across 4 stores. The range reaches A$8.53, so the distance between the first and the last listing can be wide even with a handful of sellers. You activate the key in Steam or another client, and it is worth checking the price history first. This is an add-on, so you also need the base game to play it. That costs A$2.06 today, which puts the pair at A$6.56. 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.
