The last couple of weeks have been pretty prosperous for those that like freemium offerings. RPG fans can indulge in Inotia 4: Assassin Of Berkel, the fourth installment of the action / RPG series from international developer Com2us. You do, of course, have the option of outright buying the game which will automatically eliminate the ads and give you some in-game currency, but IAP can take care of that as well. If you like a little strategy with your action there’s Castle Master 3D, a combination of Action / RPG and castle defense. This game boasts battles of 300 soldiers on each side, but you can expect to run it on nothing less than the latest generation of devices. If you prefer something a bit more lighthearted and focusing on twitchy timing you’ll get a kick out of Cannon Cat (TMA Review). A daredevil feline, a mess of fish trapped in bubbles out in space, and some vicious penguins with helicopter “wings” make this whimsical offering a lot of fun.
