Darwinia developer Introversion has announced a new game called Prison Architect.
In it, you "build and manage a maximum security prison", Introversion's creative mind Chris Delay told Rock Paper Shotgun.
No other Prison Architect details were offered.
Subversion, Introversion's other project, is on hold.
Introversion won worldwide acclaim with strategy game Darwinia. Defcon, Multiwinia and ill-fated XBLA project Darwinia+ followed.
