Ok. As many of you know the ACS is currently only available in Universe 5 (for the US servers).
When is the ACS coming to Universe X?
That is a good question, and one that is commonly asked on the OGame Forums.
The official answer is…. nobody knows. Once all the bugs are worked out of the Alliance Combat System, then it will be deployed to the other servers.
So just be patient. Or go play on Universe 5 if you have to have ACS today.
