Showdown at Pleasance House
This mission is your first taste of real combat and your introduction to the game's cover system. You'll need to move from yellow "X" to yellow "X", pressing the "RB" or "R1" buttons to take cover and fire at bad guys who are nearby. Stay low, shoot fast, and you should have little trouble finishing this mission. The Marshal will cover you as you move, as well.
The first outlaw is hiding behind some crates. Wait for him to pop up, then draw a bead on him using the "LT" or "L2" button. Take your shot as soon as he's visible, or you'll be soaking up a few bullets yourself.
Move to the crate and take out the outlaw hiding behind the rocks in front of you. Afterward, move up and use the rocks as cover to take out the last three hoodlums guarding Walton.
After the guards are dead, Walton will show up on your map as a red skull. You have a choice here. You can either shoot him in the legs and take him alive or kill him. It's up to you, but sparing his life will earn you some bonus honor and killing him will certainly cost you some.
If you take him alive, the Marshal will take him back to town on his horse. After the mission ends, you can spend a little time looting the bodies of the outlaws you killed to find some bonus cash and ammunition.
The Marshal thanks you for your help, and this is not the last time the two of you will go into battle together. For now, though, enjoy the spoils of battle and a small increase in your fame.
