If your looking for a great experience that no other FPS game can give you MAG might be the one your looking for.
You maybe one person in a huge team off 128 players, but your squad needs you in this war. To win the round your Squad of 8 people must take your objective while your Platoon of 32 players all fight along side you and take there own objectives. While your Platoon is fighting towards the north, there's other Platoon's fighting on all sides trying to defend the enemies from getting the upper hand.
In other words, the battle is big but what you do counts towards the bigger picture. You must work as a team with your squad to defend or attack the objectives that your Squad leader gives out otherwise your team may fall.
The maps are big, you've got many objectives to complete to help you win the war. Squad leaders and order in Air Strikes, Helicopters, Parachute drops and more to help you out. There's Vehicles in the game with MG's which are useful to stop the enemy waves.
The game is full off non stop action, that you won't get tired off since you'll be attacking from different sides so its never feels like the same map. I It deserves the title MAG, Massive Action Game.
Welcome to the shadow war =)
