Apparently, equipping a USAS-12 with explosive frag rounds equals “One Man Army” mode in Battlefield 3. Nerfhammer time again, Dice?
Edit: Thanks to comments after this posting, it is said to be much harder to avoid damaging yourself in Hardcore mode while using this loadout. Still, it does rip people to shreds in Standard mode. (Note: I used to call it noob mode, but as some people (noobs) were offended, I will stop calling it that from now on. ;-))
