Only for Big Spenders!
Unless your are prepared to spend $1,000s on this game, you will always be at a big disadvantage playing Invasion. Try as hard as you may, but spending money is the one and only strategy to excel at this strategy game. Also, game is glitchy and can set you back months if your are affected. T4F is also more concerned about getting Facebook likes than providing good service and a great player experience.
