"Half Life 3" may have been confirmed after online retailers have put up the pre-order page for the game.
Swedish retailer, Webhallen, has put up the pre-order page for "Half Life 3" on their website and the pre-order page for the game states that you would have to pay 449 kr or 53 usd to pre-order the game.
Meanwhile, Valve has been allegedly hinting that "Half Life 3" may come soon and that the game could be in development right now.
The Motoring Crunch reported that Valve uploaded information about "Half Life 3" on the Steam Database.
"Valve unofficially made an announcement on the highly anticipated title. By unofficial, the confirmation was made through a leak by Valve on Steam," wrote Motoring Crunch.
Motoring Crunch then wrote, "For those who are unaware of the havoc that is going on, Steam was updated yesterday and it saw the addition of App 323900. The amazing part is with the fact that App 33900 came out with Half Life 3's logo."
However, Valve has now allegedly removed the entry of the game on the Steam database.
"This has got the fans buzzing loudly as for the first time ever; a leak from Half Life 3 actually came from Valve themselves. Of course, Valve was notified of the buzz and has hence removed the App from the listing," wrote Motoring Crunch.
Previously, Tyler Lee of UberGizmo reported that alleged references to "Half Life 3" on Dota 2's tools which run on the Source Engine 2 were found by gamers.
"It seems that in the latest DOTA 2 tools, there has been some reference made to the game. The references comes in the form of a line of code that reads, 'game hl3'," wrote UberGizmo.
UberGizmo then wrote, "Of course given how obscure this is, 'hl3' could very well refer to just about anything. However we are talking about Valve, not to mention gamers have been clamoring for Half-Life 3 so there is a good chance that 'hl3' could indeed be a reference to Half-Life 3. For those interested in taking a look at the code themselves, it can be found in %STEAM_HOME%SteamAppscommondota 2 betadota_ugcgamebinwin32toolsmodel_editor.dll."
