completely down tools, or there was a very real possibility that we would face prosecution". Slowly Introversion's finances changed again. In Q3 2010 the company was able to add Steam achievements to DEFCON which resulted in the game being prominently featured in a sale. Morris credits the $250,000 generated by the Steam promotion as saving the company. Later, Introversion's games were featured in a Humble Indie Bundle that launched in November 2011. The "Humble Introversion Bundle" sold 190,261 bundles and generated $779,026.33. Introversion used the money for the ongoing development of their next game, entitled Prison Architect. As of 26 September 2015, Prison Architect had grossed over $19 million in sales, and over 1.25 million units of the game had been sold. By the end of August 2016 when the final version '2.0' of Prison Architect was released, the number of individual players was given as two million. Their next title, Scanner Sombre, was released in April 2017, after a 9 month development stage. The game sold only 6000 copies upon its release. Chris Delay remarked that it had "bombed in a big way". Virtual reality compatibility has been implemented into the game post-release, supporting both the HTC Vive and Oculus Rift, and was released in late June 2017, marking the developer's first (and to date only) foray into VR. In January 2019, Introversion and Paradox Interactive announced that the Prison Architect intellectual property was being sold on to Paradox for an undisclosed fee, so that Introversion could concentrate on new projects while Paradox continued to support and expand on the property. On 28 May 2022 Introversion announced their new science fiction themed video game The Last Starship, which is scheduled to be released in 2023.
