Confirming once again that the
Metal Gear series is not dead, Konami is hiring for new staff to work on the franchise.
A job listing on the company's Japanese site shows that the company is hiring for "new developments" in the series, giving mention to both mobile and 'consumer' (i.e. console and handhelds, as opposed to PC, arcade and mobile) entries to the franchise.
If you fancy your luck, you can find the job listings
here.
