Every game on Steam store can easily find basic info such as:

Singleplayer
Multiplayer for PvP
Multiplayer for Coop

Yes, "every game" on Steam store page

also there a "red color" text on the steam store page, it stated:

Notice: This title runs in both standard and VR modes. It does not require a VR headset.

Means it playable on non VR pc.
