While Yacht Club is well-known for their adventures in the 2D realm, it seems they're ready to move into the third dimension.
The company has shared a job listing for a "Mid to Senior Gameplay Programmer" that will be working on something 3D. You can see the official description below.
Yacht Club Games is working on a new 3D project and is building out our 3D team (and custom engine) to complement our existing 2D team. We are on the lookout to hire a capable mid to senior level gameplay programmer with a desire to build great gameplay experiences in a small, team-centered environment!
Unfortunately there's no mention of what the project is. Could it be the 3D Shovel Knight game the team has shown interest in, or something else altogether? We'll just have to sit back and wait for a reveal.
