Also, despite Battlefield 2042's lore making very little sense if you take a hard look at it, because the lore, and the rest of the game, was clearly designed around the Specialists first, the game depicts US and Russia as the only two superpowers left on Earth. Due to climate change that ravaged Earth, the EU collapsed after Germany failed as a country, and China is not mentioned at all, which is a deliberate decision to not get the game banned in China, like what happened in BF4.
Some of the Russian involvements in the game include:
-Russian forces trying to look for some sort of lost convoy in Doha, Qatar, after the city somehow turned into the SAND LOL meme personified. (I don't know how it would be possible for desertification to reach points that all of Doha would be buried in sand)
-Russia illegally drilling oil in Antarctica, under a Russian shell company.
-Russia trying to get a lost submarine back from the Americans in India.
The lore makes it off as the Russians being a convenient scapegoat, even though the lore as a whole makes no sense. The game doesn't even have a single-player campaign, compared to past Battlefield games, to try to explain all of this.
