After nine months of being available in Early Access, the massively popular battle royale game PlayerUnknown's Battlegrounds finally launches in full for PC today, December 20. PUBG's servers will be taken offline for maintenance ahead of the game's 1.0 release, and now publisher Bluehole has confirmed they'll be down for a little longer than expected.

On Twitter today, the official PUBG account announced that server maintenance will begin at 4 PM PT / 7 PM ET (1AM CET on December 21)--two hours earlier than it was originally supposed to. However, the maintenance period is still scheduled to conclude at 11 PM PT, so PUBG 1.0 is still slated to release later tonight, as initially planned. The tweet says this extended maintenance period is "to ensure a successful and smooth launch."
