The game mechanism similar with Top War and Rise of Kingdoms mixing with TD, lack of game system innovation but nice graphics UI, oh well, great artist steals right? This game is definitely heavily pay to win but f2p still able to enjoying rewards if you're joining an active alliance and in a stable peace server. You'll be bombarded with tons of advertising to gain rewards unless you paid monthly pack, mostly are OVER PRICED, most skins are NOT PERMANENT unless you paid hundreds of dollars.
