Last year around this time no one would have understood what you were talking about if you muttered the word PUBG. This weekend it was the most played game on Steam.
The phenomenon that is PlayerUnknown's Battlegrounds knows no bounds. When I'm home, I play PUBG. When I'm at work, I watch YouTube videos about PUBG. The most recent little gem I've stumbled on is a phenomenally detailed guide to sound in the online multiplayer competitive Battle Royale-style shooter, and it's so useful. If you play the game, you need to watch this.
