In Stick RPG 2
XGen Studios is a building in Stick RPG 2. It is located right next to the Old Abandoned Warehouse's basement. This is where you can apply for the Video Game Developer job if you talk to Skye (who is, of course, the company's main producer, both in real life and in-game). You can also find a bunch of sketches for character designs hanged on the walls within the studios as an extra.
