To get extra experience and all kinds of bonus items and power-ups, you need to take out as many enemy generals as possible in Dynasty Warriors 6. They are indicated on your map as darker circles. Many of the enemy generals travel by themselves and are fairly easy to take out. However, some move in pairs, or wind up close together toward the end of the battle if the enemy starts to retreat. The last thing you want is to fight two generals at the same time, because they can gang up and really pummel you.
When you find yourself in battle with two generals, the best strategy is to draw one of them away from the other, then start working their hit points down while keeping an eye on the other. If you move in to attack a general, they usually follow you short distances to hit back, and you can use this to your advantage. If another general sweeps in and starts hitting you from behind, don’t be afraid to run away and regroup, otherwise you won’t last long.
The basic strategy for taking out any enemy general is to attack and run, over and over. Generals like to use their special moves and abilities almost exclusively, so as long as you can avoid their power attacks, you’ll be OK. Don’t expect to run up to an enemy general and hit them over and over again without them hitting back, because they usually deal out devastating blows to the unprepared. Look for visual clues that appear on the enemy general moments before they unleash a signature move.
