The entrance to Ore Chasm, which is where this Circle of Slaughter is being held, is located in Eridium Blight, right by where you found Mal for the A Real Boy series of missions. Talk inside to Innuendobot 5000 to start the missions, then head down the hall and take the elevator down to the arena; it's possible to fail the mission if you decide to jump down whenever the elevator starts moving down.
If you've done the Bandit Slaughter missions, then you will find this one to be very similar. However, you will be facing off against solely Hyperion enemies, which include Loaders, Constructors, Surveyors and Engineers/other humans. While the majority of enemies will be armored, corrosive weapons are a good idea, although you'll need to be careful around some of the humans who aren't armored. If you want a good all-around element, explosive always works.
Round 1 will begin with you having to survive three waves of enemies, which isn't that challenging, since they will be the easier ones. As the rounds progress, though, you will start seeing the more difficult enemies, including RPG Loaders, Hyperion Hawks, and even some Badass Loaders. It is during Round 3 that you will first see a Constructor, which you know is particularly dangerous. Whenever it makes a turret, take that out real quick, then go back to concentrating on the Constructor.
Managing the enemies can be quite difficult, as long as you can tell where they're coming from, as you can use the opposite end of the arena to rest. Making it to the final round is where things get really heated, with the final showdown being against a Badass Constructor. There is an optional objective in each mission to kill enemies with critical hits, starting with 10 in Round 1 and finishing off with 30 crit hit kills in Round 5. Unlike bandits, who have a fairly easy to target critical hit spot, the Loaders and Hyperion staff usually have something in the way that might make it harder to hit. So, you can ignore the optional objectives if you want, as it just gives you some more money from the mission reward.
