Has that achievement for getting 50,000 points in one wave of Anarchy got you down? Well, my brother, Bionik Kommando, and I have discovered an easy way for a 2-person team to reach the gamerscore promised land. And no, it won't have you reviving each other over and over again.
Set up your match for the Grand Central Station map. In the middle of this map is an electrified fountain that awards the "Make a Wish" skill shot. If one player kicks/slides/leashes an enemy into the air, and the other player uses their leash to pull the enemy into the fountain, both players will get the Team Shocker, Team Yoink, and Team Make a Wish skillshots, for a grand total of 425 points PER KILL, times the two of you = 950 points per kill. While this is less than the amount advertised in this guide, this method requires no guns to be purchased, and you don't have to worry about ammo. It's important, of course, to stay on opposite sides of the well, so you can pull enemies across and into the water. Upgrading your leash reuse ability as fast as possible will make this even easier. Combine Whiplashed and Bossed together for a regular 600 points per miniboss. With these two tactics together, and completing the team challenges as they arise, it's quite easy to get 50,000 points on Wave 20.
This may also be the best way to grind experience, as by the end of our run (in which we never failed a wave), Bionik Kommando and I both gained over 200,000 experience. This is a more fun and easy way to get Anarchy Master than relying on the 50 points per revive, so I recommend giving it a shot.
Oh, and give us a shot when the ease of it blows your mind =)
