Every playable character in Team Fortress 2 is a dude. But the recent release of an artist’s old work shows that Valve at least toyed with the idea of introducing women into the game’s roster.

Weird fact: there was a PlayStation 2 version of the original Half-Life. Weirder fact: it contained a file cabinet that would move to face you if you approached it.

For years, Steam has struggled with the issue of review bombing, where large numbers of users leave negative reviews on games’ pages, often because of controversial subject matter or news that doesn’t actually impact the game’s quality. Today, Valve finally addressed the problem. Sorta.

I first played Half-Life in 1998 and played it again over the last month for a series of livestreams on Twitch. It’s been 19 years since the game was released, and what I experienced in 2017 made me reassess the game. It’s a chaotic, if sometimes sloppy, masterpiece.

Here’s a cool video tribute to Half-Life 2: Episode 3 by Anomalous Materials. Oh, what could have been.

Former Valve writer Marc Laidlaw has posted a fictional letter on his site that sure reads like a possible plot summary for Half-Life 2: Episode 3.

The International 7 has come and gone, crowning a new victor in Team Liquid along the way. Whether you were on the ground in Seattle at the Key Arena or watching from home, there were plenty of sights and sounds to take in, as well as a few good signs.

Team Liquid are the victors of The International 7, a Dota 2 tournament with over $24 million in prize pool. The European squad will take home the lion’s share at $10,806,301 after an historic 3-0 sweep of team Newbee.

He’s the most bad-ass tree in video games and today’s lower bracket finals at this year’s International showed-off everything that makes the hero one of Dota’s best.

When Valve first announced that it was taking a long-overdue crowbar to Steam Greenlight and replacing it with a new system called Steam Direct, people weren’t sure what would happen. Some thought Steam was about to get more exclusive again. Others feared that Valve was only widening the floodgates. Now we’ve got…

Valve just announced a new game! It’s a card game based on Dota 2. The internet is confused and upset by this.

Valve announced Artifact, a Dota card game, during tonight’s The International 7 matches in Seattle.

More than $20 million in prize money is on the line this week in The International 2017, a tournament for the video game Dota 2 that can leave new spectators baffled. We’re here to help, in case you want to watch one of these matches and be able to tell a core from a support, or just want to be able to enjoy what’s…

This is the panel for the Group Stage of the biggest Dota 2 tournament of the year. The one that’s sponsored by Valve and has a prize pool of nearly $24 million. I think it’s time the multi-billion dollar company splurged on some upgrades.

This year’s theme for The International is all about the ocean: there are aquatic cosmetics and a campaign about a sea-dwelling monster called Siltbreaker. But this year’s special map, Reef’s Edge, caused a stir in the Dota 2 community during TI7's kickoff.

A new update to Dota 2 will try to make sure new players are always matched with nice players.

Last night, we started a playthrough of Half-Life on Kotaku’s Twitch channel. Punchy shotguns and nasty aliens make for a fantastic shooter experience, but the game begins less dramatically, with a long train ride. It’s one of the most memorable openings in gaming history, but it’s the least Half-Life thing about …

WeLoveFine, a nerd-goods merch company, won’t play host to this year’s Dota 2 International Secret Shop, Valve announced last night.
