"Content Warning," a co-op horror game in which you and a friend must infect yourself with a virus or die, quickly became a big deal when it launched on Steam on April 1. It was free for the first 24 hours of release, which was not surprising to some extent, but I don't think many people expected it to be this big: according to the Content Warning team, more than 6.2 million people played the game on April Fool's Day, with a peak simultaneous players exceeded 204,000.

"It's been a real pleasure watching your videos and we're so happy to have created something we can all enjoy," the developers said in an update posted on Steam.

Content Warning looks like a gag game at first glance, and not just because of its release date. Both the trailer and the entire premise of the game are pretty goofy, with a sort of sloppy "made on the cheap by people in a hurry" quality. The initial reaction was very positive, perhaps because publisher Landfall is known for its previous games, Totally Accurate Battle Simulator and Knightfall, which were released on April 1

: A Daring Journey - both The initial reaction was very positive, probably due in part to the fact that they were known for "A Daring Journey" - neither of which was very authentic, but both of which were actually very good.

And it wasn't just its staff member whose "content warning" was published. Staff writer Morgan Park played the game first and enjoyed it so much that he later convinced a friend to play it with him. He also discovered that Content Warning, despite being a self-described horror, is actually "like a cheesy ghost-hunting show combined with Jackass. Frankly, it sounds like a good time to me.

In their message, the ContentWarning team acknowledged that there are "a lot of bugs and server issues" that need to be addressed, including voice issues, connection and hosting issues, and camera footage not being extracted or visible.

"We assure you we are working on it," the team wrote.

"Content Warning is made by a very small development team (only five people), so it may take a little time to fix, but we promise we are doing our best to fix the problem.

Despite no longer being free, Content Warning continues to do quite well. It currently sits at #7 on Steam's Most Played chart, has over 113,000 concurrent players, and is #6 on the Top Sellers chart. Not bad for April Fool's Day.
