Batman: Arkham Underworld is the latest time killer from Warner Bros. Unlike most, this one lets you play as the villains. You’ll be recruiting bad guys, building a hideout, raiding the hideouts of other players, and completing levels with your team. It’s a mix of an adventure game and a castle builder. As such, your heroes will gain new abilities, there is PvP online multiplayer, and you can play with friends if you want to. It is a freemium game and that means it comes with some of the pitfalls you’d expect. It also has a few bugs here and there that still need fixed. Otherwise, it’s a good way to kill a few minutes.
