Valve apparently has a number of games in development, though they may not be out for some time.
Speaking to Axios, Valve designer Greg Coomer revealed that "there are multiple games in development right now at Valve, and I think they're pretty exciting ones."
Whether that means long-awaited sequels to some of Valve's most high-profile properties is anyone's guess. The company isn't known for putting out timely releases, though each game it does release tends to set a pretty high bar. The likes of Portal, Left 4 Dead and, of course, Half-Life, are all some of Valve's success stories.
Valve's handheld console, Steam Deck, has been the company's latest venture. Recently, they released a Portal spin-off, Aperture Desk Job, to mark the Steam Deck's release. It's a short simulator, really, set in the same universe as Portal. It's also only 30 minutes long, so can easily fit into a lunch break.
There's currently no information regarding a timeline for these new games, whatever they might be. Many fans will no doubt be quick to speculate what the company could have in store. But, until they reveal a little more information, speculating is all we can do.
