How to unlock the Battle at the Steamboat Complete achievement in Gun - Definitive Guide
Reed is also hard work, but if you get up onto the far left (looking from the steamboat) of grassy elevated area (near the water side, not the rocky side he regenerates in) and scare him back down to the beach, he'll sit still while while you pepper his head with sniper rounds.
The second video walkthrough (credit goes to MaHalo video game walkthroughs on YouTube) for Reed shows you on how to defeat Reed. I did not make these videos.
This is story related and cannot be missed. When the mission starts you will be in a boss battle with Hollister, take cover behind the rocks and shoot him with the Shotgun which deals the most damage, once his health reaches a certain point a cut scene will occur, and when it ends follow the compass and Hollister will run out at you pumped full of dynamite, retreat backwards, away from him and he will blow up. (note: now that you have the Ferguson rifle, and you will want to use it for the next part of the level), continue towards the steamboat and Reeds men will come and attack you on horseback, once they are all dead another cut scene will occur and when it ends you will need to fight Reed. Your best bet is to get on a horse and chase reed, just keep close to him so that he can not regain his health and use the rifle to kill him. Once he is dead the achievement will unlock.
