Valve is sure that Half-Life Alyx will be modded to be played with a mouse and keyboard.

Speaking to Polygon, Valve's Robin Walker – known for his work on Team Fortress Classic and Counter-Strike – claimed said that he was certain it was going to happen. While Walker is not concerned about the potential mod, other members of the team are less accepting. 

"I know it's going to happen," he said. 

He continued: "There are a set of people on the team that are concerned about that. Personally, I'm not concerned about it at all. Yes, it's going to happen. I'm fine with it, for the sake of the other members of the team I don't want to say I encourage you to do it, but it's going to happen.

"I think people will then hopefully have an even greater understanding of why we decided to build the product in VR than they do now."

However, Walker is confident that people will realise why the game was developed for VR. Though, she people play a modded version and enjoy it just as much he would like to know about it.

"It will clearly demonstrate to people why we did this in VR," said Walker.

"It will be a very crisp way of seeing all the stuff we got for the move into VR. If people play [a modded version on a standard display] and say this is just as good, that will teach me a lot. I will realise I'm wrong, and we didn't get as much as we thought, and I love to know whenever I'm wrong."

Half-Life: Alyx was first announced last November, it was soon confirmed to be a VR exclusive title. However, Valve has no plans to make more virtual reality games.
