Bulletstorm

To earn this achievement, I used the map "monorail", as it has a dropkit as soon as you start the level. My starting weapons were sniper rifle and shotgun.

Three enemies run at you at the very beginning. Thump them into the air, and use your sniper rifle to shoot the one without a helmet with a headshot. You'll earn Headshot and Broken Wings. Once the other two land, shoot one of them in the head to earn Hotshot. Get the third to follow you back to your dropkit, and there is a bottle of Nom Juice on the table. Drink it, then slide or kick him into the air, and fill him with bullets from your regular gun. You'll earn Intoxicated as well as Bullet Kick or Bullet Slide. (Do the other one to a different enemy later)

Move up to the next portion of the map, where the helicopter is. Still using your sniper rifle, Find a small group of enemies and earn yourself Bluff by aiming at one enemy and killing a different one. Target another enemy and charge your sniper. Shoot at an enemy, and right before the bullet hits them, detonate it for Premature. Find one of the pods that explodes now, and charge your rifle. Shoot an enemy, and guide them into the pod (killing them) to earn Early Retirement. If it doesn't kill them, immediately switch to your regular gun and kill them while they are on fire for Afterburner. Find another pod and kick it at an enemy for Enviromental.

Go back and recharge your Thumper at the dropkit and find the miniboss. Thump him two to three times back to back to earn Touchdown and Bossed. Recharge your thumper again. Move up onto the bridge. Thump one enemy into the ceiling for Flyswatter.

Switch to your shotgun. Slide into one of the guys on the bridge and shoot him before you kick him for Torpedo. Kick one of the enemies off the bridge for Vertigo. Blow off the top half of one of the enemies for Topless. Aim at one of the enemies legs and shoot to earn Legless, or if he falls, shoot him while he's down for Splatterpunk. By this time there might be one or two enemies left on the bridge, if there are, thump one of them into the air and shoot him two or three times until he dies for Juggler.

Move up to the next area and switch out your shotgun for the pistol. (I can't remember if the gyrocopters come now, or if there are more henchmen, so if I have this part backwards comment me and I'll rearrange it)

Once all of the men from the bridge are dead, a LT cutscene will show up with three gyrocopters. Pull out your sniper rifle as soon as you see the first gyrocopter and zoom in on the pilot. Guide a bullet into his head for Skyjack. Immediately afterwards, pull out your pistol and charge it. Shoot the charged pistol at another gyrocopter for Flak and possibly Fireball (I got it one time, didn't get it another). I used my whip to bring down the third gyrocopter to save time because I didn't know of any other skillshots to use on it.

By now, you should have around 20 skillshots if you did all of them that I've named so far, so the going is a lot easier. There will be about 6-7 enemies with masks on that you'll have to shoot in the head or put quite a few rounds into. Trade your sniper rifle for the flailgun at the Dropkit. You can use the flailgun on the masked enemies to get Grenade Gag by shooting one in the head with it, and Sadist by shooting one in the body and then killing it before the flail explodes. Either way, I didn't really do too much with these guys.

Once all of these guys are dealt with, make your way back onto the bridge, trade your flailgun for the shotgun, and get ready to earn your achievement. You'll be attacked by the zombie guys and flail guys right off the bat, so you'll have to be quick. Start out with your shotgun out. Usually the first group of guys has a flail guy in it, you want to shoot him and he'll explode, killing at least one other enemy. This will give you Bombshell. Immediately charge your shotgun and wait for the next little group of guys to come in. Line up a close shot with the charged shotgun and kill two of them with the one shot to earn Burn. If you're able to, (I did) Thump two enemies into the air that are next to each other and send a charged shot into them to earn Acid Rain.

Pull out your pistol and charge it. Use another thump to send a guy up, and shoot him with the charge to earn Fireworks. You may be just about out of enemies by now, so kill whatever remaining guys there are and look for the miniboss. He'll be pretty easy by himself, so just circle him and fill him with bullets until he hunches over. Leash his helmet off, and repeat. When you leash his head off, you'll earn Whiplash, and if you haven't already, the achievement.

Some of these skillshots are a bit trickier, and rely on luck or timing moreso than skill. If some of these are proving to be too tough, try these:

Trap Shooting: Thump an enemy, kill him with your Peacemaker before he hits the ground.
Full Throttle: Kill two enemies without letting go of the trigger.
Enlightenment: Charge your pistol and get a headshot.
Gangbang: Use the flail and get two kills with one explosion.
Homie Missile: Flail an enemy, then kick him into another enemy. Detonate the flail before he reaches the ground.
Smart Mine: Flail an enemy, then kick or leash close to the flailed one. Detonate the flail before the other reaches the ground.
Piledriver: Kick or leash an enemy, then shotgun him into a wall.

So far the best level I have seen it on is collapsed building, here is a video so you can at least get an idea.

I got this automatically playing the Mall. Using only the Flaregun and chain launcher.

Firstoff i used the Thumper and sine tis mutants everything has a specific skillshot, so be shure to get the Assplosion outdoors and just as you go inside kill the bugs to the right.

Then go under the door, drink the nomjuice, shoot a flare and Thump! then use the Chainlauncher to line up some multikills in the cloose quaters. I recomend you alwso try and get the xray.
When you get outside, be shure to get the sausagefest and tripmine. Theres alwso a Droppod on the walkway so feel free to change weapons, although i did not.
My achievement popped up just as i pushed the large guy into the propeller.
I think you should push one of the smaller into them aswell.. i think its another skillshot.

But its really easy on Mall! have fun!
Hope i make sense to you! ;)

This was easier than I thought to get. My preference is Monorail because it's a small and open area and has two dropkits. But I have also done this in the Mall.

The secret is to swap out your weapons to get fresh skillshots.

If you think about it, you have about a half dozen weapons; of which you might use four most frequently. That means to get 25 unique skill shots you need about five skillshots per weapon and a handful of general skillshots.

I started monorail with the sniper rifle and shotgun. When the first three goons head your way, thump 'em - I get two flying in the air do a sniper head shot. And use the shotgun for the guys standing. At this point I refresh at the drop kit, and change the sniper for the pistol.

Now here's where it gets IMPORTANT- hit the left arrow (next the XBOX button) and see what skillshots you have available to you. Stop and think how you will beat up a goon with a skillshot that you have not used yet.

After every couple of unique skillshots, I hit that left arrow button to plan my next two skillshots.

You should aim for a unique skillshot for every shot.

There is no need to rush monorail, the goons don't come at you at rapidly like in Mall, so take your time.

BTW, I got my sniper rifle back for the 'copters, to take out a pilot.

I played at the mall, it's not a solution, it's more like a tips, while I played this stage every time that I saw a drop kit I change my weapons for get more variations of skillshots, I used all weapons of differents ways, I have easily obtained 30 skillshots and more than 17000 points.

Good Luck
