Merge TD Hero – Tower Defense – a mobile project in the genre of “tower defense”. The task of the players is simple – to protect the crystals from slugs and other creatures that slowly but surely pass into our world through the portal. Units are presented in the form of cards, they need to be combined to improve. In addition, there are spells in the hands of the commander. After a short training, an opponent’s mirror field appears at the top of the screen. His task is the same as ours – to prevent the enemy from getting to the crystals. But that’s not all, because the defeated monster is sent to the enemy and vice versa. That is, we have before us a representative of the “tower defense” genre with PvP elements. Communication between opponents takes place with the help of emotions. For completing the levels, players receive a loot box, coins and a rating.
