Okay, this has nothing to do with The Sims, but I just completed Borderlands 2's Hyperion Circle of Slaughter! It has 5 rounds, each with several rounds and you have to fight robots. This is the toughest of the three main game Circles of Slaughter because robots are smarter than the bandits or wild animals, they regenerate health and their fire power causes greater damage. Round 5 is particularly tough and proud to say that I was able to beat it! Here is a video of someone else's gameplay of Round 5 using the same character I play, Maya the Siren (each character has different abilities which changes combat strategy), to show you how crazy this round is and how awesome Maya's power is!
