For the second week, the Emperor's angels are the biggest seller on Steam. 

Warhammer 40,000: Space Marine 2 has held onto the top spot and has shifted more than two million copies since its September 9th release. The game has kept Valve's Counter-Strike 2 in second place, while the company's Steam Deck hardware rose up four positions thanks to a sale event for the older LCD versions of the console. These swiftly sold out.

Valve's hardware knocks Black Myth: Wukong one place to fourth, while post apocalyptic MMO Once Human returns to the Top Ten in fifth place thanks to the new Prismverse's Clash content, which went live on September 15th. 

Both NBA 2K25 and battle royale hit PUBG: Battlegrounds dropped two rungs down the ladder to sixth and seventh respectively. MOBA smash hit Dota 2 rose up two places to eighth, while Forza Horizon 4 returned to the Top 100 in ninth place on the back of an 80 per cent discount. 

Rounding off the Top Ten is Satisfactory which launched into 1.0 last week. Since its release, it has attracted a peak of 186,158 concurrent players, per SteamDB.
