Everyone has a lot to say in the comedy-FPS High on Life, the upcoming first-person shooter from Justin Roiland and his Squanch Games development studio. Especially the four talking guns. One of them, the shotgun-like Gus, is voiced by Curb Your Enthusiasm costar and renowed comedian JB Smoove. Hear Smoove in action as Gus in the gameplay montage video above, which also includes commentary from Roiland, who discusses what it was like to land Smoove for this game.

For some more new gameplay that shows some continuous action, don’t miss our exclusive 12-minute gameplay video from earlier this month. And take a look at the zany enemies of High on Life in the concept art gallery below.

High on Life will be released on December 13 for PC and Xbox Series X|S and Xbox One consoles, including day-one availability in Xbox Game Pass and PC Game Pass. We got our first proper look at gameplay back in August at Gamescom – where it totally blew up. We’ll have more exclusive coverage all October long as our IGN First “cover story” on High on Life continues.
