My.com has unveiled Evolution: a hybrid base builder, base defense game, and RPG.
Players have access to both story missions and a player-versus-player mode, and will have to protect their base from hostile forces using a mixture of automated defenses and direct interaction (i.e. tapping on badguys). Combat, on the other hand, has a much larger emphasis on player interaction. Your character will fire automatically but you'll have to swipe vertically in order to defend and pop out of cover, tap incoming grenades to deactivate them, swap between weapons manually, and activate consumable items like grenades and health packs.
Evolution is set to release in early April, and will be free to play.
