The Godfather II

There is a list in the menu that shows you the Executions you have already done, and ones you need, however i have completed the game and took over all the business and their are no more mobsters to kill. And from what i can tell, they only count if you do Executions on mobsters, or maybe 1 of each, Mobsters, police and civilians. so be careful not to run out of bad-guys before you finish the game.

Update: thanks to "superallyno1" for this one,

"You can get the achievement after you finish the game, If you go to casino imperial in Cuba there are 2 guys in green uniforms and they count as mobsters, so you just do most of the executions on them. If you go to the police station in Cuba, behind it you can find ammo for all your weapons and every melee weapon."

Update, I started a new game and did all of these in about 1 and a half hours, not that difficult really. The hardest part is making sure your crew doesn't kill them while your trying to do a certain execution. Your best off using them to attack a business, then when there's only a couple of mobsters left, remove all your members and kill the ones however you want.

One other thing, you have to buy the neck break ability from the upgrades list for you character.

Same as mik29 stated about the list of executions. It boils down to list of enviromental executions... weapon executions and melee executions. All have to be done before you take over all gangs or your screwed and have to start over. I got it shortly after going to Florida.

For the weapon achievements. its standing and kneeling executions per weapons. the machine gun one is the tommy gun and easy way to get the explosive one is call your guys back or remove them from group long enough to take over the spot. (you can add them back at any time) then throw dynimite. as for the one to shoot guy in shoulder just shoot in arm close to the lower part of shoulder.... it may take a couple tries but you will hear the person say something about getting hit in shoulder.. As for the melee weapons. I found a pawn shop in Florida i believe its called frank's pawnshop... there they have cue sticks and most of the other melee weappons. i believe even bottles to throw and a first story window that you can toss men out window of first story. While your taking this spot over there are so many witness out side that cops are sure to come.... just punch cops as they get out of car.. if you do not draw a gun neither will they they will draw out night sticks. Kill the cop and now you have the night stick.

I hope this guide helps..

If you have beaten the game already, and haven't yet gotten all the executions, you can still get them. There are two cuban, green army men standing right next to the Casino Imperial. The executions will count on them. The last execution I had was the throw out of window one. I thought it would be hard but there is actually two windows right in front of the Casino Imperial.

I do recommend to try to get the executions before you beat the game. It will save you a lot of trouble.

And for the neck snap execution you must upgrade the garrote wire.

For all kneeled executions, shoot the mobster in the knee with your pistol then sort through your weapon of choice for the kill. For the standing ones, I ran right up the guy after my crew member shot him then pressed the RS in with the appropriate weapon.

For the window one, find a business with windows in the front then beat up your mobster with your fists then grab him and drag him to the window. Toss him through by pressing the RS up and you have it.

Go to Don's view and check which ones you have left so you can focus on doing those. IF YOU FIND IT late in the game and you have already dispossed of 3 families, don't kill the Underboss, Capo or Soldiers of the other families until you have all of the executions.

If your crew is stealing your kills, kill all but 3 or 4 guys then point your crew outside or tell them to stay in one room by pressing the B button so you can kill the guys yourself.

I simply did all the executions styles in New York. Except for the garrot one and the snap neck one (must buy it for 1000$ in your players skill). Behind your safehouse there's every melee weapon except the Night Stick. You can find that one in the Bakery where the owner is : when you enter the owner's room, go to your left where there's a Camera, the stick will be on a small table. Like the others above said, keep your family members away. Killing mobsters isn't so hard.

TIP: Keep atleast the video store *forgot name* to the rival enemy. There you can throw people in the window. Keep also the bar place *forgot name..again* so you can throw mobsters from the roof and there are beer bottles and vodka bottles there behind the counter.

I thought i was really screwed when i finished the game and needed 5 executions. because i didn't want to restart as it was the only achievement i needed.
there are 2 sets of green uniformed guys outside of casino imperial, after the reading the solution i was looking for gansgter type people, but it's the army people guarding the checkpoints. For executions such as table/counter slam you have to drag them all the way inside. do this with your back to doors or you will end up knocking them into walls alot and killing them.
Also note that the bottle kill needs to be done inside too, as they take cover and the bottle can only be carried so far.

Just a note, I was stuck on the table one for a while, take the one of the "mobster" army from just outside the casino, drag him inside into the burnable bar, and instead of having his back towards the bar be sideways looking towards the slot machines, it'll then flash up "pull LS <- to table slam"

As far as I know, this achievement can be missed if you do not get it before the end of the game but there is a very good place to get the majority of them.

*SPOILER*, well kinda.

Whenever Eric Rohm is kidnapped you have to go to a building and kill the four or so guards and then kill the gangster who is using him as a shield. The first 4 guards you meet at this location are who you are going to get your executions on.

There is a table and a ledge where you can throw them off. Once you have killed all the guards and have got what executions you can all you have to do is go to the top and let Rohm get killed, the mission will automatically restart and all of your executions will be carried over.
