Avengers Alliance Tactics is the new Marvel game coming to Facebook. Similar to the last game, players will act as a SHIELD agent, sending teams of heroes in battles that are turn-based. In Tactics however, the map is grid-based, rather than enemies and heroes simply being on opposite sides of the screen. This new setup means that positioning plays a role in gameplay, and the 3D graphics mean the 20 available heroes can be seen from multiple angles. It’s likely that more Marvel heroes will be included further after launch. No word on when the worldwide launch will be, but apparently the game will be available in Canada shortly.
