The PSP version of the game picks up where the PS2 original left off, but takes a completely new direction as far as design. By now I’m sure even some of the PSP’s more hardcore fans would agree that the lack of a second analog stick has really crippled a majority of shooters. Some, like Syphon Filter, have managed to produce a workable interface, but most have failed. Taking this into account, Guerrilla has opted to make Liberation a top-down shooter instead, a move that so far seems to have paid off.
