The adverts for this make out like you can choose what your hero's wear in order to direct how much damage they do to enemies. You can't. This is yet another idle game were you have no control over what happens. Build a factory, wait to get money, upgrade the factory, repeat. It's the same idle gameplay with a new skin. You watch hero's getting built, but it doesn't correlate to how many hero's attack a monster. 7 seconds to build a hero, 3 spawn in the time it takes to build 1. Boring.
