If you are looking for an incredibly fun multiplayer game, look no further. Dungeon Defenders is a tower defense and action RPG released on October 19, 2011, by Trendy Entertainment. It was quite successful when it released, selling over 250,000 copies during the first two weeks. And I can see why. Some of my friends and I got a little bit obsessed with this game and played many, many hours of it because it is so addictive.
You can run through the campaign levels with a maximum of four players, and new maps and challenges have been added (like Capture the Flag!! Who can resist Capture the Flag?) that allow you to play with eight players. A neat feature of this game is that it is updated regularly, with new challenges, heroes, and downloadable content made available, which keeps it interesting. I used to play with the monk all the time, which I really enjoyed (he's really fast, and I like speed), but my new favourite hero is the Series EV, a robot that can lay down damaging beams and make a double of herself to attract and fool enemies.
Though my addicted craze over this game has faded now, it brought me hours of fun with friends and I still maintain it is a great game. Try it out with some buddies and you'll see what I mean.
