The inaugural lump of Gears of War 3 DLC, the Horde Command Pack, has been delayed.

"The scheduled Horde Command Pack release for Gears of War 3 is temporarily delayed due to a technical issue," Epic Games community manager "raczilla" said on the company's forum.

"We apologise to those of you who are anxiously awaiting to play. We know this is disappointing news as we've seen a lot of posts today showing excitement for this content. We have folks working around the clock to resolve this issue ASAP so you can all play and enjoy the Command Pack."

The pack was due for release today.

"I understand the frustration," said "raczilla", "but it would be unfair to communicate an ETA that we don't have. Better to give you solid information when we know more."

The Horde Command Pack contains three maps, four fortification upgrades, three characters and a pair of weapon skins. It costs 800 Microsoft Points, but is free if you purchase the the Gears of War 3 Season Pass.

Raam's Shadow will follow on December 13th.
