Magicka - Valve
Magicka: Tower of Niflheim, all new content for Magicka is Now Available on Steam.

As you all might know, being dead does not mean being unable to die again. What happens when you die twice? Nobody knows, but everyone is fairly certain that an after-afterlife is utter rubbish and an absurd fairytale.

What is certain is that being lost in Niflheim, the land of the dead, is inconvenient. A group of wizards learned this the hard way. So in order to get out they devised a plan - to go up and see if they can get out that way. With neither a rope, ladder, helicopter or multi-purpose ascension ointment, their only choice is to try to build themselves upwards... using the bodies of their friends!

    • In this mode, you will always start in Southern Shelf at Cleaning Up the Berg and may reset your playthrough progress as often as you like without losing any items, levels, or stats.

    • One additional ammo upgrade for each ammo type, at 50 Eridium each.
    • Two more backpack storage space upgrades, at 50 and 100 Eridium respectively.

• Addressed instances of audio distortion tied to Axton's turret and kill skills.
• (Mr. Torgue DLC) Critical hits against Midgets now register properly.
• (Mr. Torgue DLC) Rat Thief enemies are no longer allowed in Pete’s Bar due to patron concerns regarding excessive theft.
• (Captain Scarlett DLC) Fixed an issue with the "Shady Dealings" challenge where a purchase could sometimes not count toward its completion.

Missions
• Fixed an issue where players could be unable to interact with the menu when a mission that granted experience but not items was completed and not handled by the player before saving and quitting.
• Fixed an issue where players could cause the round to not fail in a Slaughter mission if a surviving player disconnects while all others are out.
• (Sir Hammerlock DLC) Thermitage is now friendlier and will no longer refuse to come play with some players.

    • Wildlife Preservation
    • Medical Mystery
