The idea of a Mecha-Anime themed FPS sounds rather good, but all in all, the result of Shogo is rather poor.
Small levels (Some are 1 or 2 rooms large) make it popcorn sized enough to tolerate, such that you can finish the game off in a couple of hours. Uninteresting characters, bad dialogue and plot come next. I just can't care enough to be interested in anything.
The 'human' mode missions have a great difficulty spike compared to really *really* easy mecha combat. quick-save/load will be used extensively.
The promise and concept are all there, but sadly Shogo just falls flat and there is not really anything positive to say about it.
