UBOAT

Initially, development of the game started in 2016 with a Kickstarter campaign to provide funding for the project. The original goal of the project was to raise CA$20,000 to fund the project but the campaign managed to raise CA$38,000 from 1,511 backers. The team developing the game are reportedly "a mix of young open-minded people and old hands at game development". Significant amounts of the game had already been completed in 2017 and according to the then most recent developer diary the game was "getting more and more full of shape".

Originally, release was planned for 2017, but was delayed to the first quarter of 2019. A beta was released to Kickstarter backers on October 14, 2018 and was updated frequently since then. However, it remained in beta until August 2, 2024, when it saw its full release. The game was called Uboot during the first few years of development.

Reception for the game is currently generally positive. Polygon writer, Charlie Hall, wrote that "there's a brilliant experience lurking in its depths". He praised the effort the developers had gone to making an authentic experience, but stated concerns about how early access the release was and that the game lacked game-play due to large amounts of bugs.
