Wouldn't buy it. While they sure are fun and good stuff for the money I am struggling with winning missions as is. Right now I'd rather buy a pink alien army. The teddy bear edition. ;)
LOL Bought the Elite army yesterday without having played the game yet.
Who knows if I'll ever use em :)
Glad the game is challenging though. I think having the base game be tough as-is is great.
Makes things way more exciting.
