Just been on the HMV website and they're advertising the creepy 'make you jump out of your skin then shoot your skin cos it may be an alien from the undead realm oh no what's that in my britches argggh here it comes again' scare fest that is dead space.
It's a good game and at £12.99 (PC) is a complete steal in my opinion. Bear in mind it's only been out a matter of months and has had excellent reviews across the board.
I'm not sure if 'enjoy' is the right word, but I had great fun playing this.
Don't forget quidco and the usual suspects too.
EDIT: I added the X360 and PS3 prices too later on. Not the best price if you have a Morrisons near you, but still very very reasonable and better than most places and the meagre 3% quidco shaves a bit more off too!
