DICE has released Battlefield 4's Winter Patch, which adds a brand new game mode called Squad Obliteration alongside the usual laundry list of fixes, balance tweaks and alterations.
Squad Obliteration is slightly altered version of Obliteration, which had you trying to blow up the opposing team's base with a bomb. It's intended for competitive 5v5 squad versus squad play, and removes parachute spawns, extends the bomb timer, and forces you to destroy the mode's three targets in order.
DICE has also improved the game’s netcode, added three new Premium playlists - Large Scale Battles, The Battlefield and Close Quarters - and made several changes to the UI. For the full list of patch notes, head on over to Battlelog.
The Winter Patch is now live on PC and consoles. According to producer David Sirland, it's about 400MB in size.
