Atari has released a new downloadable content challenge pack for Ghostbusters: Sanctum of Slime.

The Challenge Pack promises to bring “hours of a new single player experience” with two new game modes, Lonely Hero and Arcade Challenge. The new add-on content is available now on Xbox LIVE Arcade and Steam for 160 MS Points.

The Lonely Hero mode allows players to select any level they’ve unlocked and start from there, “but this time you are on your own - no co-op, no friendly teammates- just one player to combat the waves of the paranormally possessed.”

The Arcade Challenge is “designed for seasoned gamers” and “gives players a limited number of lives to see how their skills line up on a distinct Global Leaderboard.” “Players run through 5 of the game’s most challenging levels in single player mode and once the lives are up, the game is over. Player scores are automatically posted to a new real-time Leaderboard.”

You can check out a few screenshots from the new DLC below, along with a trailer. And don’t be shy to flip through our previous coverage to find out a little bit more about the game.
