If you are a fan of BF3 definitely yes, but there aren’t a lot of players playing this mode. On console it’s almost impossible to find a full server. On PC or if you turn cross-play on there’s at least one full server all the time.
It’s not an official mode for the game. The community created it in Portal and it’s called Afghanistan War/Mil-Sim. This is why the video has it in the title.
it’s a Mil(litary) - Sim(ulator). you die from 1-2 bullets, velocity physics are more realistic, trying to simulate what the afghanistan war looked like at some points
