For the past several weeks, I’ve been dabbling in Dota 2. It’s one of those RTS/action games where you take control of a hero unit and defend your base from the opposing team. Though the focus of these games is usually competitive, Dota 2 supports a pretty good co-op mode (probably the best I’ve seen for the genre). Any number of players can form up on a team, fill up the remaining slots with bots, and go up against an all-bot team in good, old-fashioned comp-stomp. The bots are available in five different difficulty levels, so it’s easy to tweak the experience based on whether the players are new to the game or experienced. Of late, I’ve found the co-op mode a great way to blow off some steam.
