Speaking of games that have been a long time in the works, Chris Hecker’s Spy Party has been in development for almost ten years , and is apparently almost ready for official release on Steam. (A playable beta has been available for a little while now.) Kotaku’s Kirk Hamilton and Jason Schreier talked to Hecker on their podcast.
Spy Party sees two players face off: one is a spy at a—wait for it—party, while the other is a sniper watching the party, who has one bullet. The spy’s job is to blend in with all the other AI-controlled people at the party, while the sniper tries to figure out which one is the spy and off them. It’s a fascinating bit of asymmetric game play that also reminds me a bit of the multiplayer in Assassin’s Creed: Brotherhood.
Update: While Spy Party won’t be available for Mac via Steam at launch, you can still get the beta of the macOS version by going directly to the game’s site; that entitles you to the full version upon release.
