Welcome to Gun! This is a pretty overlooked game unfortunately because when people think of western games, they instantly think of Red Dead Redemption or even Call of Juarez. This game was one of the first games to come out on the Xbox 360, all the way back in 2006. The game has aged surprisingly well, in that it is still fun to play despite some wonky controls. Set in Montana in 1880, you play as Colton White on a tale of revenge after your father is murdered. To get the full completion, you will have to play the game once on Easy and then cheat to unlock the other difficulty achievements, that way you won’t be tearing your hair out in frustration or completing the game four times.
Sadly the difficulty achievements don’t stack, so If you decide not to use the cheats, you will you have to play through the whole game 4 times which takes some time.
Step 1: Playthrough #1
Load up the game on Easy and just play it through. I recommend leaving the gold ingots alone until you’re ready to get them all in one continuous effort. I also recommend doing any side missions as soon as you get them so you can quickly earn money to buy upgrades to make the game even easier. When you’re ready to collect all of the gold ingots use the video in the guide to help you. That’s all there is to this playthrough, complete the missions, side quests and mine all the gold. That should net you 770 earning all achievements apart from "Insane Difficulty Complete", "Hard Difficulty Complete" and "Normal Difficulty Complete".
Step 2: Difficulty achievements
If you decide to not “cheat” (which again, I strongly advise that you do just to save yourself the time and frustration), then you will need to do 3 separate playthroughs on each of the difficulties to unlock their respective achievements. See “Insane Difficulty Completed” for more details on how to unlock all of these in 20 minutes.
Step 3: 100% + Mop-Up
The last stop of the game. In this step, you’re going to want to complete all the side missions, mine all 44 gold ingots that are “hidden” around the world, as well as purchasing all of the upgrades from the various traders around the map. You can complete the side missions legitimately or by using the same tactic as the difficulty cheat. See “Insane Difficulty Completed” for more details.
This game can be very laid back and enjoyable or extremely hard and frustrating depending on if you use the easy method, which I really can't stress enough that you should absolutely take advantage of it. However you do it, congrats on another smooth completion. Hope you had fun!!
