Mainframe Liberator is a strategy game by Nokia for our Nokia N97 or N97 Mini, where we have to get “hack the system”, for which we need to extract data of red or yellow files and destroy the “black agents” 
.
It is certainly a very original game, which I liked most of all created by Nokia, which will block to block files and to obtain all their information, before being intercepted by the “black workers” to which we can destroy throwing blocks on top.
The game has a very good tutorial explaining to do.
