Microsoft expects the Ninja Gaiden 2 mission pack will return to Xbox Live sometime today.
The mission mode pack was released last Friday and then yanked down after it caused technical problems like systems freezing (surely not a problem usually associated with Xbox 360 oh wait now I get it).
Most of the niggles have been fixed, according to Gamerscoreblog, and those who already have the DLC can begin playing again.
The Ninja Gaiden 2 pack adds 12 karma and 12 survival missions; the former is based on totting up the highest score, while the latter offers you one weapon to fend off an endless stream of baddies.
The mission pack costs 800 Microsoft Points (GBP 6.80 / EUR 9.60) and also incorporates 10 extra Achievements.
Ninja Gaiden 2, released in June, is a gory spectacle of swishy swords, severed limbs, and taxing gameplay, although it's not as fiendishly difficult as the original game.
