What would a highly anticipated product launch be without a few snags in the road? It seems that Microsoft may have made a mistake or two with their limited edition Halo 3 tin packaging. The boxes which incorporate pieces of real metal into the package construction are the problem here. Apparently the discs aren’t held in place well enough. Once the disc slips out it comes into direct contact with the exposed metal surface, damaging the surface layer of the disc beyond repair. Thankfully, Microsoft has already recognized and admitted the issue, and is offering to replace the discs free of charge for anyone afflicted by such tragedy. Best get your replacement disc quickly though, as you only have until the end of December to cash in.
