The Joker confirmed for Mortal Kombat

Villain of the moment to appear alongside Batman

Upset that the untimely death of Heath Ledger means you'll never see Batman battle The Joker again? Never fear, as Midway has just confirmed they'll both be playable characters in Mortal Kombat vs. DC Universe.

The developer confirmed four new characters at the San Diego comic con over the weekend. According to IGN, they will be Shazam, Liu Kang, the Joker, Jax, Kitana, and the Green Lantern.

Some new gameplay modes were also revealed. A close combat feature allows players to get the camera up-close to the characters and trigger some hard hitting combo moves unavailable in normal play.

Freefall mode was also demoed, where characters knocked off the edge of an arena can continue fighting in mid air as they plummet down to the floor below.

Also mentioned was the reason Superman isn't invulnerable. He's susceptible to both kryptonite and magic, apparently.
