Compare Alpha Protocol prices across trusted key stores and find the best deal. Developed by Obsidian Entertainment. Published by SEGA. Released on 6/1/2010. Available on PC. Genres: Action, RPG. Metacritic score: 73/100.

Obsidian's spy RPG where every conversation is a skill check and your paranoid choices reshape a genuinely reactive thriller. Rough around the edges, brilliant in the bones.

Alpha Protocol is a third-person action RPG from Obsidian Entertainment built around a single audacious idea: what if the dialogue system in a spy game mattered as much as the shooting? You play Michael Thorton, a deniable operative burned by his own government and racing to stop a geopolitical disaster that keeps getting messier the deeper you pull the thread. The premise is pure pulpy espionage fiction, but the execution underneath it is a proper Obsidian RPG dressed in a leather jacket and wearing a wire. The heart of the game is the Stance and Reputation system, which tracks how every major character perceives Thorton across the full campaign. Push handler Mina Tang too hard and she becomes cold and withholding. Charm arms dealer Scarlet Lake and doors open that a more hostile Thorton would never find. Antagonise the wrong handler at the wrong moment and mission parameters shift in real time. These are not cosmetic changes. Handler intelligence briefings, available safe houses, and even which bosses show up at the finale all flex based on accumulated relationship scores. For people who care deeply about whether choices actually propagate through a narrative, this is one of the most genuinely reactive western RPGs released in that era, full stop. Build variety runs through five skill trees covering pistols, assault rifles, shotguns, stealth, and technical gadgets alongside a suite of tradecraft passive abilities. A pistol-focused Thorton who maxes Brilliance (the pistol super-move that briefly pauses time) plays like a completely different game than a stealth-spec operative ghosting through the same missions without a single kill. The problem is that early game combat is genuinely unpleasant for almost every build until the skill investments kick in. Guns miss shots that should connect, enemy AI occasionally forgets the concept of cover, and the checkpoint system has the patience of a handler who has been waiting in a van for six hours. The rough edges are real and deserve acknowledgment, not apology. The writing, however, is doing serious heavy lifting. Dialogue choices run on a timer, forcing you to commit to a tone (professional, aggressive, suave) before you have finished processing the scene, which creates a kind of character emergence that slower RPGs rarely achieve. Thorton becomes whoever you panic-click in a crisis, and that unpredictability makes replays feel fresh. The supporting cast - particularly the gleefully unhinged villain Leland and the morally ambiguous Halbech contacts - are written with the kind of layered self-interest Obsidian does better than almost anyone. Filler quests are mercifully sparse; the game is short enough (roughly 12-15 hours per run) that it never pads. Three to four playthroughs to see the major story branches is a legitimate recommendation, not a punishment. Alpha Protocol is a game that requires you to meet it halfway. The third-person shooting is functional but never inspired, and a 2010 Unreal Engine 3 budget shows in every texture. But if you can tolerate clunky gunfeel in exchange for a spy thriller where lying to a contact in act one closes a door you needed in act three, this is one of the most interesting RPGs Obsidian ever shipped, and it shipped without the fanfare it deserved.

Rough combat and dated visuals are the tax you pay for one of the most genuinely reactive dialogue-driven RPGs Obsidian has ever made.

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.
