Great location. Great coworkers. Lifesaving games.

Located in Chicago’s River North area, Level Ex®’s fast-growing game studio is transforming the way surgeons hone their skills by practicing high-risk surgeries with the latest medical devices in our industry-leading mobile, AR, and VR titles.

Our games are built using state-of-the-art graphics and physics tech, and deploy an arsenal of well-designed game mechanics to capture the thrill and challenge of performing real surgery. These games increase dramatically in difficulty as the player progresses, and are carefully crafted with professional level design, compulsion loops, flow channels, and deliberate gameplay balance. Backed with a mature art pipeline and latest-gen engine tech, we’re able to recreate surgery with spectacular realism.

Our engine has earned the trust of the country’s leading physicians; plus we’ve custom-built real-time fluids, tissue shading, and soft-body systems to enable a wide range of realistic new game mechanics.
