Introversion's paid alpha of Prison Architect has already garnered the company more than $100,000, according to a report from Eurogamer.
The alpha, which launched on September 26th, is price tiered much like Kickstarter; contributors who pay within certain tiers get different rewards. Directors Mark Morris and Chris Delay revealed the sales numbers at the Eurogamer Expo. The 2,667 pledges they detailed were spread across every category, with 1,801 backers paying the base amount of $30, and four springing for the top $1,000 level.
"We feel like this approach that we've taken has been really successful," said Morris.
In Prison Architect, players build and manage a maximum-security prison. The developer duo demonstrated several new features, including prisoner tunneling, door locks, riots, and gangs. Players can expect these features in about a month, Delay said.
The alpha is still available for purchase on the Introversion website.
