This is an amazing game, I have been replaying the entire campaigns in SOE in anticipation of the new Mercenaries game. I really recommend taking advantage of this sale which there are a few days left, the game is worth way more than $5 and you can unlock units to play in the free multiplayer Mercenaries sequel as you beat each SOE campaign. I have not seen another iOS original strategy game with this amount of polish. I agree with the above posters in that you can't approach this game like other typical cookie cutter TBS. Your turns happen simultaneous with the enemy so you must anticipate his actions.
So it is! Great news, no? Hahaha, well for those who haven't grabbed a copy of Scourge, this is your chance.
Just bought it.... I like my strategy games nice and simple like advance wars but for this price and given the love for it I'll give it a punt
