At first glance Assassin's Creed Rebellion looks quite a lot like Fallout Shelter, which isn't a surprise considering they were both developed by Behaviour Interactive. But unlike Fallout Shelter, Assassin's Creed Rebellion's gameplay is centered around turn-based squad strategy mechanics more similar in style to the X-Com series.
Bug Heroes 2 is the sequel to an iOS game that never made it over to Android, so bear with me as I get you up to speed. This series has garnered high reviews due to its compelling mix of tower defense and twin-stick shooting action. It packs numerous heroes into squads and tasks players with spilling enough bug guts to improve these characters over time. When you combine this quriky premise with rather appealing graphics, it becomes somewhat easy to understand this game's success.
The sequel expands on the original by introducing new heroes (such as a Bumblebee boxer and Waterbug pirate) along with plenty of enemies to keep the action fresh.
