First of all, great game! Although I enjoyed it a lot more when I was just starting the game, I think that this will be one of the best Zombie-Games of the next few years. However, I am a noob! Sadly. I am only around 25% percent through the Main-Story and less through the Side-Quests. I was watching someone stream the game before I purchased it, and he was LESS progressed through the game, and had better weapons than me AND he could buy ammo from the Trade Stations! How! Lol, I love melee in this game, but I really love the peace of mind I get knowing that if chupacabra goes down, I have a fully loaded AR with 2 mags and 1911 clipped to my left leg. How do you unlock the ability to buy ammo/guns? Now I do have guns, I have a few police weapons and a military weapon and I had a pistol but I gave it to the peace of chupacabra that I don't want to give spoiler alerts lol. So I have guns, but how do you buy them/ammo?
