They Always Run

This is probably around 30-45 mins in, depending on skill. Before you fight the big robot, you will meet with the rat, ensure you don't say you are gonna kill him! Later on, when you fight him, you can either kill him with attacks, or take him alive by taking him down with attacks. You can replenish these attacks by counter attacking him with just before he strikes. After he is down, play through some more of the mission where you have to carry his body, before the mission ends. At the start of the next mission, carry his body along to the right, following the dialogue, until you reach a three story building. Go up the ladder outiside and into the top room to turn in your bounty.
