Hitman: Blood Money

I personally found 'The Russian Hare' was the easiest rating to achieve for this to unlock. It is incredibly easy when played on the easiest difficulty setting, and I recommend you play until you have at least unlocked the final tier at the Kruger Schmidt store in-game. Select the W2000 and equip it suitably. Below is the setup I chose to load my W2000 out with:

Scope 2
Silencer 2
Double Capacity Clip
Lightweight Frame
Carbonfiber Barrel
Extra Ammo
Armor Piercing Rounds

Avoid the Bolt Action for this particular run, as it will make things more difficult than they need to be. The Armor Piercing rounds in my mind seem to make the W2000 much more potent, and the recoil is not that severe despite what it tells you. Once you have your rifle loaded out suitably, select the mission 'A New Life', as it is much easier than the rest to complete this achievement on. Now, to earn The Russian Hare you must not kill any civilians. I did not shoot the dog in the garden either, but you may be able to.

When the mission starts, keep an eye on the jogger and steal the donuts from the back of the catering van. When you get the chance, poison them back at the starting location. You can use the Poison Syringe for this without jeopardising the achievement. I can confirm this as I have done so. Now they are poisoned head to the white 'Lauritz and Co.' van across the road from the house. Open the rear doors, drop the donuts and carry on. The screen will split in two, showing the two agents eating their donuts and dropping dead.

Walk away from the spawn location and head towards the garbage truck. Across from it is a woman gardening. Wait till she is facing towards the road, and zip past into her garden. In the garden, head into the tree-house. This location is going to be vital to you for ensuring this achievement comes easily. When here the woman is oblivious to your presence, even when you are firing – the second silencer ensures that you can remain here for as long as needed. Look through the window towards the pool at the target's house, and watch out for any FBI agents. Pop into the scope and ensure you can hit them. Due to the AP rounds most shots are fatal, but I recommend aiming for the chest regardless to be sure. Some of the civilians will see the dead body lying, and then they will make things easier by actually calling more guards over. The guards will inspect the corpse, and you can pop a cap in their backs while they are completely unaware. Continue to rinse and repeat until only the Pool Cleaner, the wife, and the Clown remain. The Caterer does not come outside that I am aware, but avoid shooting him too if he does. Note that the AP Rounds can punch through a second target and take this into consideration when going for a kill.

Once the supply of enemies has dried up, check your map and see how many are remaining. By this stage the FBI may have called in the back-up limos, but these provide little problem as the guards will go to investigate the bodies. Pull the trigger and they can meet up with their buddies again. When you get a quiet moment, reload the W2000. If there are enemies outside the front of the house you can leave your W2000 in the tree-house, and check to see how many there are. If you choose to leave the house and use another vantage point, then by all means do so. Pack the W2000 back into its case before embarking on the trip though to avoid arousing suspicion. When in position assemble the rifle and continue the slaughter.

After all the FBI agents are dead and you are absolutely sure, it is time to bump off the target, Vinnie Sinistra. Keep the rifle on you, and click the right stick in once, so the game is like a first person shooter. I found Vinnie at the top of the stairs, but he can also be found in the tiny room beside the room he watches TV in. Either way, shoot him with the W2000 and begin the search for his wife. Because you cannot kill her, things become a little more difficult. From my experiences she seems to sprint between the house and the pool where the dead agents are lying. When she heads through the door into the garden from the house or vice versa, inject her with the sedative. Steal the Microfilm, and then leave.

This may seem extremely drawn out, and depending on how you play things it may well be. It can take roughly 20 minutes if you are thorough. The map is your absolute best friend, however. Tap LB and search through all the screens until you find any blue circles moving around. Shoot those moving circles and ensure that you are thorough. When you are done, the achievement should pop up fairly quickly. Congratulations on your extra 20G, and enjoy the newspaper clipping on the assassination too!

To gain a Special Rating you must kill every possible hostile enemy on a particular mission with a miscellaneous / unique item. These items or weapons include such things as hammers, Baseball bats, nail guns, garden shears, kitchen knives, spades, screwdrivers, stilettos, etc. (Although in some cases some enemies can be killed by other means but most of the time you should kill them all with one of these specifically).

The civilians and secondary targets on these missions can either be left alone, sedated, or killed with the same unique item as you killed the hostile enemies with, however killing even one civilian with any other weapon has a high possibility of negating the achievement. In my opinion you should kill every single human being (and even some animals if you can) with the same unique weapon, just to be sure.

One of the easiest ways to accomplish this is on the mission "A New Life" and on recruit difficulty (this is also much easier when you have the kevlar and painkillers equipped). Get one of the unique items on this map, either the garden shears, which can be seen in use by the woman cutting her privet on the opposite side of the road to the witness' house, run past her and to the back of her house, when she follows you try to grab the shears and kill her as fast as possible. You can also use the kitchen knife found in the kitchen of the witness' house or the baseball bat found in his garage.

Now the shears and bat are the most deadly but they cannot be concealed, the kitchen knife can be hidden and can be smuggled into the house via the caterers box. With the unique item in hand proceed to kill everyone on the map, if you are using the kitchen knife begin silently, kill the two garbage men around the corner, the clown, the jogger, the caterer and then move in and kill the easiest bodyguards one by one. If you get compromised, don't panic and reload, just try to get into a protected area and stab the enemies as fast as you can and use your painkillers at the best time. The methods with the bat and shears are basically from the compromised part, you will instantly be seen carrying those weapons and immediately fired upon, you must get into a good location with cover and kill enemies with stabbing or swinging motions. Behind the garden shears woman's house is a good place. Kill all the bodyguards and their back-up then move into the house and kill the target and anyone left.

Once you are satisfied that everyone is dead, make a quick sweep of the map and then finish the mission. If you used the Garden Shears you will unlock the 'Insane Florist' special rating, if you used the Kitchen Knife you will unlock the 'Sushi Chef' special rating and if you used the Baseball Bat you will unlock the 'Slugger' special and the achievement for any of them.

I've posted this video courtesy of 'GameVideos47' to visually illustrate the 'Insane Florist' method:
*Note that killing every single civilian and the guard dog may not be necessary.

This is a video, courtesy of 'Tomtokamoto' showing an alternative method on the same mission, he uses mainly headshots to gain the 'Russian Hare' special rating (you may want to mute this):

Thanks and don't forget to upvote, please post any questions, improvements, or any new ratings you find.

This achievement's pretty easy. Go onto "A New Life", I recommend on Normal cause they die in less hits. As soon as the level begins run to the veterinary surgery (across the road from the target's house) and run round the side to the window at the back. The woman in the garden next door (cutting the hedge) will get alerted and run round the back of the vet to find you. Just stand there with a gun or syringe equipped and she will panic and drop the hedge cutters. Quickly run and pick them up and stab her in the back with them. Now, you'll either get caught or someone will find her body after a while so just wait round the back and pick them off one by one as they come close. After a while if people stop coming to investigate the bodies you can preoccupy your self by running round and killing the garbage man fixing his truck or the woman gardening next to the treehouse. Check your map regularly to make sure you get everyone before you escape.

If you're still having trouble buy the pain pills and/or health boost to help you out.

After completing the mission, making sure EVERYONE is dead, and escaping, you SHOULD get the "Insane Florist" special rating.

Kill all guards, the mission target, and the woman who has the jewelry with ONLY the kitchen knife and you will get it. The hardest part is sneaking in and grabbing the knife undetected, but once you do, kill the lone guard in the basement, take his suit, and slowly take out the rest of the guards without being seen or causing noise. Towards the end, even if you are finally caught in the act and the last few enemies swarm in on you, it shouldn't be too hard to swing away and kill them off.
