How to unlock the Defend the Hideout Complete achievement in Gun - Definitive Guide
When you reach him, he'll request you hold the front, which is a really easy task. Mount the gatling gun and spray some lead! When you're done spilling some blood you'll have to talk to Port who asks you to stop the cannon. It's blue and pretty hard to miss, dispatch the enemies near it and head towards it (when you get very close some enemies will jump out from behind some rocks, they aren't very threatening though). Once you've mounted the cannon, you'll notice you have unlimited ammo again so just keep firing.
This is story related and cannot be missed. When the mission begins follow Chavez to the bridge, pull out your new Sniper Rifle and hold off the enemies, if they get too close use your normal rifle. Keep killing the enemies until Clay can get the gatling gun working again. When they are all dead go down to Clay and hop on the gatling gun, keep shooting all of the enemies that appear and once they are all dead go and talk to Port. Next you will need to make your way over to the cannon, you best bet is to use the sniper rifle to kill whoever is on the cannon at that time and then use your rifle to pick off the other guards, take it slow especially on harder difficulties and once you get to the cannon press to use it, kill all of the enemies that come towards you and once they are all dead the achievement will unlock.
