OOH OOH, let me explain!
Mag stands for ¨Massive Action Gaming¨, Years ago, a company named Zipper Interactive (who develops SOCOM series) disapeared and let the SOCOM game making to Slant Six, also known as ¨Can´t Fix¨ due to their bad games, but then Zipper showed up MAG, wich is a first person shooter for PS3 only, totally different to SOCOM, the game is based on that you are part of one of the 3 mega clans (wich I don´t remember it´s names), those clans send small groups to make missions like scorting people and such, the 250 player thing is true, all these 6 groups do their missions on DA BIG FRIGGEN MAP, and if you ran into another clan group, kill em´.
