This is what Tyler McVicker of Valve News Network claims to have learned from his sources. He has previously mentioned Citadel, but now emphasizes that the mix of first person shooter and real time strategy elements makes the game perfect for the Steam Deck. “Think Left 4 Dead, Alien Swarm, real time strategy and Half-Life having a baby.”
However, there would be no work within Valve on Half-Life 3 or a direct sequel to Half-Life 2: Episode 2, despite the latter ending on a cliffhanger. Last year, Valve released the VR game Half-Life: Alyx, which takes place between the first and second game.
The Steam Deck is a portable game console that plays games from the Steam catalog. The handheld comes in 64GB, 256GB and 512GB of built-in storage. It has a starting price of 419 euros. The Steam Deck should have been shipped to those with reservations in December, but has been delayed to February 2022 due to material shortages.
