Seattle-based developer Z2Live looks like it has two solid hits on its hands.
MetalStorm: Online, the company’s follow-up to casual city builder Trade Nations, has pulled in at least 2.3 million players since its launch on May 12. The aerial combat app is free so these numbers reflect a decent debut. Plus, the app’s ranking hasn’t declined too dramatically since launch. It’s at #45 today in the U.S.
Z2Live is one of handful of venture-backed mobile developers, with a recent second round of funding led by Draper Fisher Jurvetson. At the time, it had a single hit, TradeNations, which was developed with the help of Canada’s Bight Games and is perennially on the iOS list of highest-grossing apps.
With MetalStorm, the company’s moving into more hardcore games. But it’s still sticking with the freemium model with monetization through in-app purchases. MetalStorm: Online sells coins in packs ranging from $0.99 to $49.99 and it’s been consistently ranked in the top 50 highest-grossing title in the U.S.
The app has 1.2 million players in the U.S., 330,000 in China, 308,000 in Japan, 216,000 in the U.K., 177,000 in Germany and 154,000 in France.
