Valve showed a new game in the Half-Life universe, called Half-Life: Alyx, the events of which occur between the first part and the second. At that time, Alyx Vance and her father Eli led the resistance against the Alliance.
This game is from scratch designed for VR. The duration of the new Half-Life will be approximately the same as Half-Life 2. The heroine will control objects with gravity gloves. The game was developed under the Valve Index, and will also work with HTC Vive, Oculus Rift and Windows Mixed Reality. Owners of the Valve Index will receive the game for free.
Valve wants to further develop the franchise but first will see how the audience will accept the game. Campo Santo also works on the game.
By the way, write if you are waiting for Half-Life: Alyx.
