Total War: Warhammer is off to a fast start. Sega announced today that the PC strategy game has passed 500,000 sales since launch on Tuesday, helping the game to become the "fastest-selling Total War title on Steam" ever.

In a press release, Creative Assembly studio director Tim Heaton said sales at this level make Warhammer a "runaway commercial success." Additionally, he shared that the game "regularly" eclipses 100,000 concurrent players.

According to the Steam Stats page, the game had more than 98,900 concurrent players today, May 27, at peak.

Creative Assembly also reminded players that they have until May 31 to get the Chaos Warriors Race Pack free when they buy the game. As announced previously, this comes with three new Legendary Lords, additional units, and more mounts, among other things.

GameSpot's Warhammer review scored the game a 9/10.

"When you're in the middle of a siege and you're coordinating an assault with a friend, Total War: Warhammer approaches perfection," critic Daniel Starkey said. "You’ll be tested on all fronts and asked to manage complex battles with broad, nuanced outcomes. Every system and piece feeds into others, and your choices make all the difference. It's a triumph of real-time strategy design, and the best the Total War series has ever been."
