Microsoft has issued an apology to Halo Wars subscribers over the recent data loss incident.
In what the studio describes as "an unfortunate incident", all statistics on the game's Xbox Live leaderboards, including all single-player, multiplayer and Trueskill data, were reset to their original launch day status.
"This was human error related to Xbox Live servers. It is not a broader service issue and will not impact other titles or Xbox Live experiences. The Xbox Live team is investigating the cause to prevent this from occurring in the future," said Microsoft's Major Nelson.
"I'd like to apologise for the incident and any frustration Halo Wars players have experienced in having their statistics disappear from the leaderboards."
