This game has such amazing graphics, the game play is unique and very well done, there is no resource gathering or base building for units, but you can build defence turrets. The lack of base building is not an issue as there is so much more to think about to complete your mission. The amount of different cards that are available is vastly more than any RTS game has done before, and on top of that you can upgrade every card to get new abilities and improve them.
The campagin is long and does require more players in some missions, the pvp option is interesting, challenging and fun. Overall this game is a must have for RTS fans, best of all it is free to play online. Give it a go I promise you will have fun.
