Call of Duty: Elite PC still in development

Activision has moved to reassure PC gamers still waiting on the launch of Call of Duty: Elite that their patience will be rewarded.

Activision producer Noah Heller told Eurogamer the PC version of the service has proved to be tricker than expected.

"Unfortunately I don't have an update for you at this time. We're still working on it. We can't date it yet. It's a challenging piece of development. It's really all I can say."

Heller said he used to be a PC game himself and is "excited to do right by the PC players soon".

"Unfortunately I can't give you a date at this time - look, it bums me out to say it," he added.

"I get several emails a day. It's a vocal, passionate audience. What we need to ensure is that when we ship something for them, it's quality. We cannot make them wait this long and then deliver something that isn't quality."

One other delayed Elite service - a tablet version of the tie-in app - is making better progress, but also goes undated.

"It's built specifically for that platform, and built with this two screen idea in mind, the idea people are going to be playing the game and might have this on their lap, to check with their friends to see what their progress is like in real-time," Heller said.

Call of Duty: Elite is a social network which launched alongside Modern Warfare 3. Registration is free, but premium subscribers get early access to DLC at no extra charge, plus a range of exclusive features and tools.
