It's time to bust stuff up in a cross-platform manner. Aerena - Clash of Champions has arrived in the Play Store after debuting on Steam (coming to iOS later). This is a turn-based combat game that promises quick, high-energy matches with squads of cool heroes squaring off. It's free-to-play, but the model doesn't sound bad. Note: it's tablet-only.
Being a turn-based game, Aerena is a tactical experience. Each hero has its own unique skills and abilities, so your strategy must change based on what you're working with. The game includes a rotating roster of units and heroes to deploy, but you can also purchase (with cash money) your favorites to keep in the roster permanently.
The developers promise new content will be added frequently, and you are able to earn in-game currency from completing challenges. It'll take a little grinding, but it sounds like a reasonable proposition in this age of freemium games. The graphics look sweet too, so it's at least worth checking out.
