Bulletstorm

Go the the anarchy map called Ulysses. When you start go to your left and you will see two glowing teleportation units that are blue and black. You need to kill all of the enemies in one wave by kicking or leashing them into those units. You will know if you do it right by getting the skill shot "black hole fun". I got it easily on the first wave.

EDIT: This tip comes from Tardii

"If you stand in the corner right in front of the right teleporter all the freaks will go to the platform right above you. All you have to do is run over between the teleporters and leash one of them and then run back to the glitch spot and let your leash recharge."

Not much to this cheeve for the amount of points on offer. Using the Ulysses map, you will clearly see the 2 teleportation devices across from each other, its as easy as leashing or kicking the enemys into the devices and getting the skillshot black hole fun.
Be aware of the electricity above the door if you leash them down from the raised section, other than that its pretty easy, best bet is wave 1 or 4 depending on your level as you get only grunts(higher levels can spawn harder enemies), i also found kicking to be a safer method as mentioned above sometimes while leashing i would accidently get a shocker skillshot, and try not to kick 2 guys in quick succession as sometimes the 2nd guy would fly thru to the other side as the 1st guy gets zapped and it didnt give me the skillshot for the 2nd guy.

I hope this helps,you need to kick the creatures into the glowing blackholes,but be careful,try to kick one at a time!Best wave to do this on would be wave 1.Here's what I did, it should help but be patient,when you kick a creature into the blackhole more will spawn and come into that room,run around the space station and they will clear out,go back until you feel comfortable enough to kick an enemy into the blackhole.Normally when you run around and go back there will be one maybe two,but then just run around space station again and it should clear out the middle where the blackholes are,I don't know why but they leave.Please be patient,it took me around 10 min.It can be frustrating because there was times when I kicked a enemy that I had already downed before it went into the blackhole but it gave me 10 points and it didn't say "black hole fun".I hope this helps.Ask me if you need more help and I shall reply.Thanks,Oh one more thing if you should fail,don't restart wave the creatures were different and harder,don't know why,just exit and then restart.

Best done on Wave 1. Simply kick or leash enemies in the teleportation devices. I say "simply", but it actually took me a while because I either kept getting the Grafitti skillshot or a +10 kill. Anyway, try to isolate each enemy so you get a clear line to the device and kick away. If enemies bunch up, try taking a quick lap around the map's perimeter. Not a complex achievement, but it can get frustrating if enemies die some other way. Stick with it and you'll get it.

This achievement can get frustrating because all the other suggestions suggest kicking the enemy into the teleportation device. The problem with that is they don't always go the way you kick. If you're too far away, or too close, they can hang on the rail or slide down the wall and you get 10 points instead of the 150 for the teleporation kill. Which messes up getting this achievement.

The easiest way I found to get this achievement is by playing with two players. Have one player stand down below under the stairs and have the other stand across from them behind the window on the other side of the teleportation device.

Of course you are not going to shoot this entire match. Depending on which player the enemy comes after, the other player will leash them and pull them into the teleportation device. By doing it this way you can line up your angle when you leash the enemy and pull them into the teleportation device perfectly every time.

You can do this on stage one easily enough, just remember to move around if you're getting beat up to stay alive. If you die, no worries, when the enemy runs after the other player, he runs around, kicks you back to life, both players set back up and continue until all enemies are dead in the match.
