What Strategy Should I Employ For Doing Elimination On GRAW 2?

Go slowly, choose a weapon that can give you some distance from the enemy, but close up will do some ripping damage to the enemy when they get nearby.  The enemy AI is not particularly smart on any setting.  They do run towards you and they can walk away from you.  If you are playing this by yourself, use the drone and stalk the enemy as if they are your prey.

If you are working as a group, you can split into two groups, Alpha and Bravo and then you can pincer move on the enemy.  But be careful not to shoot each other.

Since you can only share one drone, it is best not to split too far apart.  You don't want to have the drone running the far end of the map and you don't want to be running all the way down the map to save someone who is flashing orange. (Injured)
