Rough economy, Gunslinger achievement help

I got the economy achievment by luck. What I had was a sniper. And kept shooting in a group of enemies. And got 3 for 1. The gunslinger, I should have. But for some reason it didnt unlock when I killed him with a pistol. But what you do when you start getting sniped from that 4 story building. Once you jump through the window. Run up stairs. Get the pistol on the table. Run back behind the wall. Waste your bullets. Then once the russian guy comes pull out your pistol and you should have 80 pistol bulluts. You will need those. Then once your where you are going to assassinate the general. Take out his sniper, that is at the tank with him. After that. Pull your pistol out, and once you see him run for more cover. Shoot your pistol. This took me I would say 2 hours to do. If you doint succeed. Pull out a grenade and commit suicide. I would say these 2 achievments, either your a call of duty god. Or it's all luck if you can get these easy.

You kill 3 enimes with a sniper and I dunno the second 1

To get the 3 for 1 bullet special you need to be using a sniper rifle. A good place to get that one is right before you try to assassinate General Amsel. While you are providing cover fire, there is a building across from you sniping spot with germans on a balcony. The Germans are firing at the street below so all you need to do is line them up right in front of you. Another good place to get it is near the end of the game during DOWNFALL. I believe it is in Reichstag where I got my 3 for 1. There is a spot where the Germans are all bottled up and one after another they come out in single file through a barricade. It is inside the building and they are coming around a curved promanade from the right side. I think it is after the part where you go to the updstairs balcony and get the sniper rifle, but I'm not positive about it since I did it sometime last week.

For the rough economy, I actually got it in Zombies.I got the PTRS and into a group of Zombies and got it. As for Gunslinger, I'm still trying but I've almost got him as he runs from behind the Tank.

A lot of people don't know this, but you can actually unlock the Rough Economy achievement in Nazi Zombies, thats how I got it, so just get them to line up and then shoot with a sniper. Its really easy.

To get Gunslinger you need to shoot him in the head with pistol

I got the rough economy achievement by using the .357 magnum on zombie mode

I got rough economy with the Trench gun they were all in a line shot them and I got the award.

I got the Rough Economy achevment when your attacking Shuri Castle as the americans ( the last level with the americans) when you go underground into that small bunker thing and theres four guys sitting in the room, I shot through three of the four and knifed the last one

I got the Gunsliger achevment when the general was in the car I moed him down with the pistol
