We’ve seen how the hero will operate in my game so now it is time to take a look at how the enemies behave. In solo games that I’ve played, I usually see two extremes where either the enemies have a very simple “seek and destroy” routine or highly complex set of routines that are “if-then” dependent or randomized in cards or the App’s operating system. I think both can work well but it depends on the game’s other factors to see it come together and make for a great game experience.
