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.
