Where to buy The Callisto Protocol - Final Transmission at the best price? As of 8 Aug. 2026 this title has one offer, C$19.49 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 C$8.19 today, which puts the pair at C$27.68. 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.
