To get this achievement, allow yourself to be hijacked, but immediately hijack it back for the achievement results you are looking for.
From Undead_.-._Lord | Dec 23rd 2009
killa is wrong, you need to be hyjacked, then hyjack the same vehicle less than 10 seconds after getting hyjacked
try and get someone to help you out on this one, like zelda said
From zelda71000 | Sep 7th 2009
this is a tricky one and is normaly easiest if you achievement booster since you have to get hijacked then re hijack it (or you can just try asking people and sometimes thell help you out). remember this has to be done in lone wolves (or some other ranked free for all such as mythic brawl wich only is around for like 3 days a month)

Triple Kill In a ranked free for all playlist (Online) Kill 3 enemies within 4 seconds of one another.
From KnockEmDead1996 | Aug 3rd 2012
The easiest way to get this achievement would be to play a free-for-all playlist with a close range and powerful weapon like the energy sword or shotgun. Use the weapon wisely and you should get the achievement in no time.
From zelda71000 | Sep 7th 2009
play in lone wolves (its the only ranked free for all playlist thats always around, sometime mythic brawl comes around tho)and keep playing and hope for rockets or swords(if its swords than you can get steppin razor at the same time).

Overkill In a ranked free for all playlist (Online) Kill 4 enemies within 4 seconds of one another.
From KnockEmDead1996 | Aug 3rd 2012
To get this achievement in the easiest fashion, grab a rocket launcher and shoot towards a mass of enemies in a free for all playlist or do the same thing with full health, an energy sword, and a shotgun. Weapons must be used wisely.
From zelda71000 | Dec 23rd 2009
This is easiest for most to get if you play in mythic brawl or ranked living dead(both of which are double exp weekends, so if they arent around youll need to play in lone wolves). If its mythic brawl then sometimes there will be rockets(due to the aproximately 10 players its easy to get a killtacular which {since its on a mythic map} will get you the killtacular acheivement also). If your on ranked living dead try to be last man standing in a small room and throw a grenade when they rush you and you should get a lot of kills(ive got a killamajaro like this{7 kill}). In lone wolves(even if boostering) this one is extremely difficult so just hope for rockets or swords on guardian(the only reason why boostering is hard with this is because normaly groups of 4 boost so someone has to be killed twice which means they have to run to the person after responing and get killed quickly and the the kill times between the people has to be about 3 seconds{leaves little room for error}).
From Undead_.-._Lord | Dec 23rd 2009

From KnockEmDead1996 | Aug 3rd 2012
For this achievement, you are going to have to be a good precision shooter. Just aim at a person with your spartan laser and shoot them in the right or left arm. If you are lucky, the laser should continue to fly by the person killing them and hopefully killing a person that could be behind them.
From superbird5005 | Mar 9th 2010
This one you more than likely need luck on this one. If you find two people not playing and they are standing next to each other, then go right ahead and melt them like it's cool :D. Other than that, it's most likely a good idea to either have some friends help you with this, or luckly have two people in front of your laser.

Too Close to the Sun In a ranked playlist or in campaign destroy an enemy Banshee with the Spartan Laser or Missile Pod.
From viceaa5 | Sep 15th 2009
Play the mission Covenant and don't die or use up the ammo on your spartan laser until you get to the stage where there's Hornets on the ground and heaps of banshee's in the air. Then use the spartan laser and blast down a banshee( This might be hard to get because it's hard to aim perfectly) then the achievement is yours!!!!!
From zelda71000 | Sep 7th 2009
play the mission the covenant(i dont think the difficulty matters as long as you have a spartan laser which i believe you spawn with no matter the diffivulty or settings) and after clearing the beach and killer the AA wraith and cheiftan at the begining of the mission walk a little bit ahead of the warthogs and mongoose and look at the sky and there should be some banshees just laser one and youll get the acheivement. Note this unlocks the scout body armour variant( also its the acheivement that unlocks the armour not the action so if say your game messed up and you didnt get the achievement then the armour wouldnt ulock either)
From greenandy06 | Jul 9th 2009
On the mission the covenant on legendary after the warthog gets droped off getinto it and drive where the hornets land and then there should be a banshee that's when you get out destroy it with your spartan laser.
From 0600Hours | Jun 12th 2009
If you are looking to do this acheivement on a ranked game, I'd recommend playing on Sandtrap, as it has Banshees, Spartan Lasers, AND Missle Pods.

Used Car Salesman In a ranked playlist or in campaign destroy a vehicle that has 3 enemies in it.
From Forgoten_Scars | Jun 1st 2010
There are multiple ways to get this achievement. If you're having a bit of trouble, pick a level with many opportunities in it, such as the level titled "The Covenant". Your first opportunity will be soon after you start the level. Since you're already given the Spartan Lazer at the beginning of the level, you shouldn't have much difficulty finding something strong enough. Once you get to the area where you have to enter the barge your way into the first tower, you should face a Wraith. Backing up the Wraith should be a Prowler. Simply shoot the Prowler with your weapon and you should get the achievement. Later on in the level, you will have to face two Scarabs. Once you start to wear these Scarabs down, enemies should come in vehicles from the base of the large building. Find a way to blow up the vehicles in one shot, and you should get the achievement. I would suggest blowing up the first Scarab and landing on the ground. Avoid the attacks form the second one and blow up a vehicle with 3 enemies in it with your Spartan Lazer. Best of luck to everyone.
From viceaa5 | Sep 15th 2009
In the Ark mission get to the bit where there's Prowlers and brutes, go to the crashed ship where there's a rocket launcher, pick it up and wait for the prowlers. When they get there aim with the rocket launcher at ONE prowler and shoot for the front of the vehicle ( shoot a little before it gets on your aimer ) and then the achievement is yours!!!
From ressurection666 | Aug 3rd 2009
The easiest way to unlock this achievement is in the second mission when the first Phantom flies into the hanger. Use one of the turrents and destroy it.

We’re in for some Chop In a ranked playlist or in campaign destroy an enemy vehicle with equipment.
From Forgoten_Scars | Jun 1st 2010
The only way I was able to get this achievement is to go through the mission titled "Tsavo Highway". Somewhere near the end of this level, you will get to an area where there are people hiding in small buildings up on a hill. This area will be right after you have to cross over a broken bridge and take on the enemies on foot. Halfway through, there will be a Phantom that flies overhead, if you need a reference point. Be sure to go by here and pick up a trip mine. One should be hidden somewhere inside the small, open buildings. Keep progressing for a while and you'll find an area where Brute Choppers are going everywhere. Be sure to get behind them and shoot off all of their armor. Wear them down with whatever weapon you have (Preferably some form of plasma weapon that does little damage to the actual body) until they're almost dead. Once done, simply get one to charge at you and lay out the trip mine before ducking to get out of the way. If done properly, you should blow the enemy up with this trip mine.
From zelda71000 | Sep 8th 2009
play the mission tsavo highway and get a fuel rod and a tripmine. then shoot a chopper twice(2 times)with the fuel rod and drop the trip mine under it and 99.9 of the time youll blow it up and get the achievement.note the other .1is caused my game lag normaly and it causing tripmine or full rod to register funny.
From (HW) Raxzor | Jun 9th 2009
ON Tsavo Highway get the mine where the brute choppers appear when one drives by you throw it

Fear the Pink Mist In a ranked free for all playlist or in campaign kill 5 enemies with the needler.
From Forgoten_Scars | Jun 1st 2010
Easy way to get this would be to find a level with a lot of Drones or Grunts. They seem to be the ones that carry around a needler most often. Once you steal one from one of these enemies, simply kill 5 others and the achievement will be yours.
From ressurection666 | Aug 3rd 2009

This is on your first mission(the one right after the cutscene mission, and this takes place in a forested area). Right before the end of the mission(the part where you get into the pelican after freeing johnson and several marines) go up along the rim of the building(there was a jackal sniper up here) by jumping on the low wall where there where two jackals right next to the bridge the cheiftan was on) and folo that all the way till you reach a dead end and you should see a skull which you hit right bumper to pick up like a normal weapon and your acheivement SHOULD UNLOCK(i have incounted issues with the skulls before so watch out{such as them not appear in the skull screen but achievement unocking and vice versa}).

Black Eye When playing on Normal, Heroic or Legendary difficulty find and claim this skull.
From zelda71000 | Dec 23rd 2009
On the mission the storm(i recomend playing on normal due to the ghosts) play through untill you reach the out side with the AA wraith (a purple wraith is also dropped off within about 30 seconds or so of the door being oppened) then go down the ramp by the enterance and youll see some white crumbled walls and a carrier warthog. Flip the warthog and drive it over to the cylindrical building. Park the warthog right next to the fron side(the side with the purple wraith, this is the place where the gorund is the highest) and jump on top of the warthog(i advise throwing down a buble sheild here to prevent getting torn to peices by the ghost{and possibly the wraiths}) and jump crouch onto the top of the building(to jump crouch you ust jump the hit left stick to crouch while in air) and it should be their(it is possible to get up there to fast and youll have to wait a few seconds for it. Also IF YOU DESTROY THE WRAITHS IT DISAPPEARS)
From kickur244 | Nov 19th 2009

In the mission floodgate, continue the level as you normally would, but as soon as you reach the first steps, look a top a building to your right, inch forward, continueing to look at the building, as soon as you see a flood jump, shoot that mo fo down, he's got the skull. If it lands in an unobtainable place, simply restart the mission. If you for some reason need help, my Gamertag is Korabar, but I don't think you would need help.

Famine When playing on Normal, Heroic or Legendary difficulty find and claim this skull.
From legends55 | Jan 15th 2010
In the mission the covenant, start from the very beginning, this is important, the skull doesn't show up unless you start at the beginning. Proceed on to the beach, where you first get your hornet. Instead of traveling on to the second tower, move on to the first tower. (Can be viewed at by the beach the hornets are.) Finally, land, and move up the big ramp in the center of the outpart of the tower. The skull should be up there.
10
Tilt When playing on Normal, Heroic or Legendary difficulty find and claim this skull.
From kickur244 | Nov 19th 2009
This is the easiest skull to get.Start on the level "Halo" and go into the caves. When you reach the two way path to the right or forward(If you see a metal platform, go back), go right. Go to the end of the trail and right in front of a boulder, the skull is waiting right there for you to pick it up.

From Forgoten_Scars | May 26th 2010
Heroic isn't all that hard to do. All you need to do is have patience and slowly wear down your enemies from a distance. Use carbines for headshots and plasma pistols to take down shields/power armor. For the flood, just use a brute shot blade. It'll take down just about any of them in one hit.

Campaign Complete: Legendary Finish the Campaign on Legendary. This also unlocks the achievements for Normal and Heroic if not yet earned.
From Forgoten_Scars | May 26th 2010
Your best bet at getting this done is to use certain weapons on certain enemies. For the normal ones, use a carbine for headshots. For brutes, plasma pistol and then a headshot. Hunters need grenades. Flood can be taken out with the blade of a brute shot. Use the right weapons and it shouldn't be too hard to get through Legendary in the Campaign.
