At just $21.99 on eBay, this RE5 Chainsaw USB Drive was only included in the Asia-bound limited edition bundle — also comes with a 3-disc “Making Of” DVD set. Auction page.
I’ve seen at least two more RE 5 sets that have different freebies. Fortunately, you don’t have to look for the right Limited Edition or shell out lots of money if all you want is the chainsaw.
