PC shooter Red Orchestra 2 has smashed publisher Tripwire Interactive's records, and made a shed load of cash.
Within two days of launch the game generated more money that its predecessor did over five years.
Launch week sales broke all Tripwire company records, outselling Killing Floor by a three-fold margin.
But despite this success, Tripwire admitted the game endured a "rough launch".
"We've been working diligently since launch to get these issues sorted and have made great progress fixing issues with matchmaking, VOIP, and stability as well as improving performance," Tripwire said.
"The final major area that we've been working on is stats, player progression and ranking."
The company said it has now fixed all the major issues with the stats system via a recently released update - but this has forced a reset.
"Due to the problems with stats and players either earning stats and achievements that they didn't actually earn or earning stats at many times the intended rate, we are going to have to do a global reset of all stats for the game," Tripwire explained.
"This means all achievements, stats and player progression will be rolled back as if all players were new. This was not an easy decision for us to make, but one we felt we needed to do to preserve the integrity of the stats and ranking system, and to provide all of the players the best experience with the game over the long term."
A "special bonus" will be given to all players as compensation: double experience.
"This means if a player plays the game during the double experience period they will quickly get their experience up to where they would have been had these issues never existed.
"Additionally, we are going to give those playing the game during the double experience period a special achievement called 'In B4 Reset'. Right now this is just an achievement, but we're going to be looking at ways to give special rewards to the players that have this achievement in the future."
