Bad control of attack, cannot target the boxes in front. Unable to control movement during attack, most likely to be blocked by enemies. Assistant does attack enemies. Some times assistant kill all enemies when blocked by them and then directly end the terms without any chance to get any box. Overall, uncontrollable and load slowly each term, waste data.
Quite good. Though AI ally is so bad that you cannot win those stages asking for ally survival. The free weapon stage is absurd, who will play the same stage 500 times or more to get the pieces. Then, you need to grind for gold to even pay for the cost. It urges people to quit, not play more.
