MAG, the MASSIVE ACTION GAME has you plotting against four other teams (as mentioned in our previous article). Finding weaknesses is best discovered by playing on each of the four teams and learning for yourself how you defended those positions. 

Knowing from doing seems to be the best tactic here and once you've seen it from both sides, your knowledge of the area will allow you to adapt and overcome most obstacles with relative ease provided you and your teammates are a good shot and can hold down an small region at a time.   MAG gives you get lots of signals and there's a howling siren to warn all forces playing that an area is secured, as a barrage of helicopters will rush in allowing your squad and team players to respawn in those helicopters before pushing forward so taking them out during an area takeover is anti-productive.

MAG Walkthrough PS3, MAG Walkthru Strategy Guide, MAG Walk through Guidebook There isn't much more to tell about this game without experiencing it for yourself, the multiple tasks and well defined objectives are too numerous to mention without reading through the tactical GameGuideDog Walkthrough for MAG, but I will say that you will be playing a good 80 or more hours before you have a full grasp of all the locations, ins and outs of all the maps, and where the weak spots are for your enemies.
