Opening and ending sorties aside, its handful of missions could be tackled in any order, and your dialogue and combat decisions would fundamentally alter both future options and how folks perceived you. It was an RPG wrapped around a sub-Metal Gear stealth shooter. Released in the same year as Fallout: New Vegas, Alpha Protocol was Obsidian's big experiment in having a smaller but more reactive story. While undeniably buggy, poorly balanced and with only half-functional mouse and keyboard controls that rendered several mini-games nigh unbeatable, it still had a lot going for it, as Alice Prime explains here. Hopefully this means that the game may return at some point, or - wishful thinking, I know - get a sequel or other revival, but at least not all hope is lost. While just speculation on my part, the game's removal from Steam seems likely related to Microsoft buying out developer Obsidian, and potentially taking the Alpha Protocol rights with them. As reported by cheery RPS fan-site PC Gamer, Sega's music licenses for the game had expired, and while Microsoft have purchased Obsidian, Sega still hold the Alpha Protocol rights. Update: Sadly, the reason for de-listing the game is as mundane as it gets. While much maligned at launch and best played with a gamepad back when such things were unfashionable, it was a sneaky RPG well worth experiencing at least twice.

While no longer for sale, players who bought it during its nine and a half years of availability can still download and play it, and keys from other sellers should still work. The game's store page confirms that it was removed from sale at the request of the publisher, Sega, whose rights for the game has expired.

Obsidian's quirky espionage RPG Alpha Protocol is the latest to be de-listed from Steam.
