Gun Cheats

Defeating Hollister
Sneak up on him and shoot him once. Then, run off and get behind a rock on top of risen ground in the middle of the arena. When he is circling the rock your are behind, you should also circle as well. He will eventually stop and yell at you to come out. He should pace back and forth slowly while you hide behind your rock. When he stops and is not facing you, shoot him in the head. Perform this until the point that he becomes too smart to fall for it again. By then his health should be low enough so that you can run out and keep shooting while strafing. After you have gotten his health down all the way there will be a intermission sequence. Look at your compass at the bottom of the screen. He is the red dot. Find him and he will run at you. Run, but keep firing at him with your pistols and he will blow up.

Use Quickdraw with your Dual Peacemakers and he will explode.

It would help if you have purchased the shotgun speed loader, extra shotgun ammunition capacity, and the extra health slot upgrades. When you start the fight. Hollister knows where you are. Sneak up into the rocks. He will not know where you are until you reveal yourself for the first time. Once you do, he will know where you are for the rest of the fight. Keeping that in mind, sneak up on him without being seen with your shotgun equipped and fully loaded. Once you are behind him, get as close as you can without being seen, as shotguns do the most damage when up close. Then, just fire away with your shotgun as fast as possible. Do not forget to drink your whiskey when your health gets low. Note: This works under the normal and easy difficulty settings with no shotgun upgrades purchased.

Defeating Reed
Never let Reed out of your sight. If he is by himself and you cannot see him, he gains life.

This is very difficult at first. Before you start the mission, go back to Empire City and Dodge City and get as many weapon upgrades as possible. Do about 60 to 70 percent of the side missions beforehand. Use the upgrades for mostly the rifle and bow, and the health upgrade for your horse. Once you bring these stats up, go to the mission and defeat Hollister again. Then, defeat Magruder's riders. Once that is done, open the safe and Reed will show up. You will start behind a rock. Take out the newly acquired rifle obtained from Hollister, get on the horse to the left, and chase after him. Keep shooting him. It will take about three minutes to kill him. Do not lose sight of him, or his health will go up.
