Co-op horror title Content Warning was the fifth biggest seller on Steam last week.

The game is the latest surprise hit on the platform, in part thanks to its free-to-keep model. Content Warning launched on April 1st – outside of this week's chart data – with players able to claim the game for free in its first 24 hours. After that, it went back to its regular price of $7.99. This has helped Content Warning attract a playerbase of over six million people almost overnight, something that has prompted the title to receive a lot of attention from the influencer community.

First place once again went to Counter-Strike 2, while Helldivers 2 retains the No.2 spot. Valve's Steam Deck hardware rose up two places to third, charting ahead of Call of Duty. Activision's shooter has returned to the Top Ten thanks to the launch of the Black Cell (Season 3) DLC for Modern Warfare 3. That content made its debut in eighth following its April 3rd release.

Battle royale hits PUBG: Battlegrounds and Apex Legends both dropped down the rankings this week; the former fell from fourth to sixth, while the latter slipped four places to No.7. Cyberpunk 2077 also made a return to the Top Ten in ninth, up two positions week-on-week.

Rounding off the Top Ten this week is Bethesda's The Elder Scrolls Online, which shot up from No.36 to tenth thanks to a 75 per cent to celebrate the game's tenth anniversary.

Here is the Steam Top Ten for the week ending April 9th:

1. Counter-Strike 2, Valve
