Alpha Protocol™

Alpha Protocol™

For players who want an agent story where mission decisions shape Michael Thorton's future, Alpha Protocol™ offers a focused single-player premise. The current price of $6.79 from GOG gives you a concrete point of comparison against your budget; it makes most sense when this choice-driven story fits your plans now. The Steam PC version is listed for Windows. An upcoming Steam sale window can serve as another reference point, but it does not promise a discount or confirm that the game will participate. You can weigh $19.99 at GOG against the next announced Steam sale window, Dec 17, 2026 – Jan 4, 2027; participation and a discount are not guaranteed.
