How to see the game version? I cannot find it anywhere. Please help. THks.
"C:\Program Files\Steam\steamapps\common\left 4 dead 2\left4dead2"
Or similar path (C: may be different for example)
In here, open the "steam.inf" file with any text editor (like notepad) and see what it says next to "PatchVersion". As of today, it was 18.104.22.168 for example).
