its funny you should mention gamestation and the pre order bonus content. i believe its called the resistance pack. i phoned gamestation yesterday to pre order a copy and was told that if i wanted the resistance pack then i needed to get the ltd edition and not the standard edition. But to my knowledge there isn't any ltd edition only a resist edition but thats pc only!!!! oh and to top it off the ltd edition is £5 extra and they need a deposit lol of £5. i thought it sounded dodgy so i told her i would leave it for now!
I am a PC player ( yes we exist ) and bougth it here cause is much cheaper than in Spain , where i live. All i seen in amazon and in Spanish on-line game sellers is the resistance editions, with only the unlocks as add-on.
