It is very challenging and satisfying that is because you will be rewarded with new weapons as you frag your way to victory in different game modes like DM, Team DM, Search and Destroy, and Domination. Leveling up and getting new bonus items has never been this fun, get new weapon add ons as you get points for fragging and following the mission objectives. Use counter UAV and also air support for an advantage against the opposite team.
The game is very fun especially when you have to use team work to complete missions, one example is Domination. Take control of multiple control points and gradually get points for the team. There are lots of other multiplayer game types to play. It will keep you busy for hours.
