Freemium titles are popular these days, well, because they’re free. Add the enticing combination of Ninjas and Martial arts tournament fighting and the formula almost solves itself. It’s a cash cow. Shadow Fight 2 has garnered a whopping 5,000,000 downloads in less than half of a month, taking a sharp katana to the face of existing premium fighting titles already in the marketplace. The franchise’s humble beginning started on facebook and had a very successful run on iOS devices, so the momentum was already primed for an Android release. Shadow Fight 2 eventually snuck its way onto Android to a not so stealthy response, but more akin to sake enriched Sumo wrestler in a China shop. So far for developers Nekki, Shadow Fight 2 has been a total success on the Android platform.
