I bought it a few months ago when it first came out after hearing the hype. I thought it was OK, just got way too repetitive so flogged it after a week. Thoroughly original though and nicely violent.
its great, follows on from the sneaking of MGS but with the mor intuitive controls from vice city and the rest. definitely one worth keeping for an occaisional play of an evening just in from the pub all dark and in need of some mindless freedom of expression. :-)
