Major Nelson received accurate information this week indicating that the Xbox "deal of the week" would be Bionic Commando Rearmed for 400 ($5). A small reminder: to take advantage of the deal, you must have an Xbox Live gold membership, otherwise it'll show as the standard 800 ($10).
It's also worth noting that the Metacritic average for BCR is an 85, while the super new and flashy Bionic Commando is 70. Which one is getting five of your dollars?
