The original Worms landed on the Play Store way back in early 2011 (when it was still the Android Market), but the launch was far from perfect. Device compatibility was lacking, and force closes all too common. A while back, the game was actually removed from the Play Store.
In fact, it was the Worms franchise's new owner that requested it be taken down. According to Team 17 Digital, EA was "not supporting OS updates," and the company asked for the game to be removed because it "didn't want to damage the brand." Yikes.
