Guts: use them or lose them in the free action MMORPG Dungeons & Dragons Online: Eberron Unlimited (DDO). Get a good grip on your sword and get ready to swing—if you think your heart can take it. So bring your slay game, but leave your wallet at home, ‘cause this game is totally free.

Yeah, that’s the sound of rotting bones crunching under your feet. And that’s a flesh-shredding blade trap, and past that is a mind-blowing puzzle that you have to solve if you want go deeper. But right over there is a big, bad ogre looking to smash you down with a tree-sized club and stomp your brains out through your ears—just for kicks.

You’re in charge of all the action here. When a gang of now-you-see-me, now-you-don’t, now-you-have-your-soul-sucked-out undead creeps come after you, this fight isn’t going to operate on remote control. Block, swing, throw, trip, cast, dodge, tumble, and cleave, and if you can avoid being torn into human confetti by their clawed hands or having the life force sucked out of you to feed their unholy lust, then it’s time to show these freaks that undead is nowhere near as dead as they can get. Pick the best weapon in your arsenal and get in there.
