The studio’s first game, Two Point Studios, is a spiritual successor to classic simulation title Theme Hospital.
Two Point has around 20 developers, including veterans of titles like Black and White, Alien: Isolation and Fable.
The studio is currently working on “several exciting unannounced projects”, said Sega, with further news promised for the coming months.
“We’re delighted to welcome Two Point Studios officially in to the SEGA family,” said Sega Europe president, Gary Dale in a prepared statement.
“As a relatively new, British-based developer with a global hit already under their belts, we knew we had to move quickly on this deal because they are an extremely attractive investment proposition with a great deal of talent.”
Mark Webley, co-founder of Two Point Studios, added: “It’s a landmark step for Two Point Studios and we’re thrilled to be joining the Sega family. We’re looking forward to executing the next phase of our plans as we continue to evolve Two Point County.
“It’s a hugely exciting time to be a part of Two Point and we are today thanks to the hard work, passion and dedication of our small, but amazingly talented team here in Farnham and the incredible fans that have supported us throughout and guided our continued development of Two Point Hospital.”
