Half-Life 3 testing has begun according to Valve leaker

According to Gabe Follower, who has previously leaked details about Valve's new Half-Life game, codenamed HLX, Valve has recently opened up play testing for HLX, which is believed to be the codename for Half-Life 3, based on clues found in strings of code. HLX is now beleived to be in the ‘friends and family' testing phase, which is typically where more leaks begin to occur.

Gabe Follower had previously leaked a ton of Counter-Strike 2 and Deadlock details after those games entered wider playtesting. With that in mind, if this rumour is true, we may begin to get more concrete details on the new Half-Life game very soon.

If this portion of testing goes smoothly, we should see Valve officially announce HLX in 2025.
