Sega have released a short selection of gameplay videos from Sonic Lost World. The segments show off both Silent Forest and Frozen Factory. Whilst a lot of it has appeared in previous trailers, some of it has not.
However, unlike previous trailer footage, this video does not have a song playing over the top, all the audio comes from in the level. There is one exception in that there isn’t any stage music which is odd, but you do get a much better idea how these stages play, look and sound.
