The Tomb Raider Underworld: Beneath the Ashes DLC will not be released tomorrow as previously planned, due to "an unexpected technical issue".
A spokesperson said: "An unexpected technical issue means that Beneath the Ashes will not be available to download on 10th February as planned.
"We apologize for this delay and we are doing everything we can to bring you this exciting new content for Tomb Raider: Underworld as soon as possible."
The 360-exclusive DLC adds new levels which "send Lara back to the remains of Croft Manor where she uncovers a massive series of never-before-seen caverns and age old crypts used to protect and hide a deadly source of power."
We'll bring you an updated released date the moment we have it.
