There are three modes and the co-op mode is interesting. It is quite awesome to share between two players' chess pieces. unfortunately, those chess pieces along with combination effects and the skills are all basically from the original Auto Chess. Although it is much easier to get started, it lacks the spirit of this game's characteristics. The item system mainly draws on the original Auto Chess as well, the of drop rate is acceptable, there is no synthesis but there is an upgrade, but these items have to be upgraded three times to the fourth in order to have new special effects, the second, third upgrades are the same after. So only co-op mode gives me a fresh play experience rather than Auto Chess and Dota underlords.
