Ratings and reviews

Great in the beginning, but cards are too hard to get and the random merging makes it hard to have the cards you need. The down grading of weapons, you've worked hard to get, is disappointing. I play this game daily, but I have to drop my rating to 1 until game play and card mechanics are improved. A mechanic that needs to be added is a way to disassemble cards. That way when they NERF weapons, you can try for other ones.

Honestly kinda entertaining, but fell off quick. It ramps the same enemies to be chunky and requires high lvl towers to even compete. If you didn't RANDOMLY get lvl4 or lvl5 tower that helps because an enemy can just evade you with flying. Well you're boned. The random aspect is really tiring and a waste of effort. Why do you have to take multiple towers that you will not drop in the field. If you trash that set of 3 to just RANDOMLY get the same 3 you just trashed.

Started off really fun but then it comes to a point where the game is basically unplayable. Not enough resources to pull for better cards and no way to get gems unless you pay for them in order to advance gameplay. The fusion system kicks out the same cards over and over so no advancement there either. I really like the game but these issues turns a good game into a really bad one. If you're looking for a decent game, Wall Brawl is the way to go.
