Sounds brilliant. Looks like it will play back the events leading up to Desmond's arrival at Abstergo. Although if it is all that FPS gameplay, i can see it dragging. Still the environments looked varied so i suppose it'll be nice to look at.
And the sections with Desmond using the Portal esque platforms was pathetic. People with sense should avoid this if it's more ooh make a path across here and then get stuck because you don't know what to f**king do with no clues whatsoever from the useless AI.
