I bought MAG, and I think it's pretty fun actually.
The 256 is accurate while deceiving. You actually only play against 32 enemies at a time. I'll try to explain the game using MSPaint. :biggrin2:
The game type (domination) is split into 4 quadrants each with 64 players. The quadrants are split into 2 competing factions (Raven, Valor, or S.V.E.R.) of 32 players - 4 squads, 8 players each. One faction is set to defense and one to attacking.
The defending team is supposed to guard their 2 objectives (i.e. A & B for Quadrant 1 defending team) while the attacking team is trying to take them over in every quadrant. There is a damage bar that is underneath the objectives on the screen. The more objectives the attacking team takes, the faster the damage bar fills up.
The game is 30 minutes long, and the attacking team must fill up the damage bar in that time period to win. So all 4 attacking teams in the game are working towards a common goal, but will only play against 1 defending team each.
Hope this makes sense.
