PC games firm Valve has insisted that the upcoming Half-Life Alyx isn't going to be delayed and has made other releases in the popular series free on Steam.

In an AMA event on Reddit, some of the development team answered questions from the community, with Valve staff saying that the game is done aside from a few tweaks to the very end of the experience. Concerns about delays are, of course, due to the fact that the third entry in the Half-Life series has never emerged in addition to Valve's perfectionist style of development. 

"Lots of us at Valve, as well as playtesters, have played through the entire game multiple times," the developers wrote.

"Right now we’re primarily polishing and fixing bugs, which is where we’d hope to be at this point in the development cycle. We’re confident we’ll hit our intended release. (We let the Valve Time happen before we announced the game.)”

Valve has also made the previous entries in the iconic games franchise free until Half-Life Alyx's release in March. The title was announced in November last year and follows the Steam giant rolling out new virtual reality hardware Index VR.

Since Alyx's reveal, that tech has been slowly selling out around the world and as of last week, it was only available to buy in Japan.
