High on Life, the upcoming comedy-FPS from Rick & Morty co-creator Justin Roiland and his Squanch Games development studio, has revealed its voice cast, and it features Rick & Morty alums, stand-up comedians, sketch comedy legends, prominent video game voice actors, and many other funny and talented people.

Roiland plays your first talking gun, the pistol-like Kenny (who sounds quite a bit like Morty). Curb Your Enthusiasm’s JB Smoove voices the shotgun-esque talking gun Gus. Comedian Betsy Sodaro plays Sweezy, the Halo-Needler-like gun you can see in our exclusive 12-minute gameplay video from earlier this week. Tim Robinson, from Netflix’s I Think You Should Leave, plays Creature. The Sarah Silverman Program costar Laura Silverman voices Lizzie, while MadTV alum Dave Herman plays Gene, the alien at your house who gives you your bounty-hunter missions. The bloodthirsty Knifey is played by YouTube cartoonist Michael Cusack. Other notable names in the cast include Kids in the Hall troupe member Kevin McDonald, stand-up comedian Maria Bamford, Nathan Drake voice actor Nolan North, Solar Opposites costar Thomas Middleditch, prominent video game voice actresses Jennifer Hale and Tara Strong, and more. Get a look at some of these characters 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.
