Revolution is a wonderful adventure game developer located at: http://www.revolution.co.uk/
They have been of much support to the ScummVM project, permitting us access to the source code for their games Beneath a Steel Sky, Broken Sword 1, and Broken Sword 2.
The ScummVM team has also released a freeware download of Beneath a Steel Sky, thanks to the gracious help of Tony Warriner and the rest of the team at Revolution Software Ltd.
