Description: Completed the Campaign on Legendary difficulty.
Gamerscore Worth: 125G
How to Earn: Legendary is much harder in this Halo then others in the past as the AI is much tougher. Here are tips on how to complete the campaign on Legendary:

-Conserve your ammo. Running out of ammo is severely dangerous. Enemies already take a large amount of bullets, and there isn't much ammo to be found laying around. If you do find yourself out of ammo for a weapon, swap it for anything. You need to have a weapon no matter what.

-Be patient. Nothing will get you killed faster then running out of cover blindly.

-If you need to, run out and see where enemies are at to get a feel of what's to come.
Save your grenades, they will become your lifesaver. Use them only in extreme measures and taking out large groups of enemies.

-During any portion of the campaign, be on the lookout for the "Drop Shield" ability. This is the best ability to have during the game. It shields you from enemies fire/grenades, and heals you while you are inside it.

-Always be on the move, never stop and be in one area. Enemies will just point all their fire at you and kill you almost immediately.

If the enemy is far away, try not bring attention to yourself and just start shooting. Plan where you are going to go and plan ahead.

Gamerscore Worth: 50G
How to Earn: This achievement can only be unlocked in Matchmaking within any competitive playlist. The achievement requires you to earn a Double Kill medal (2 kills within 4 seconds of each other) with the Shotgun. The easiest playlist to get this achievement is within the Living Dead playlist, as you spawn with a shotgun if you are a human and the zombies are fairly easy to kill. This achievement can be unlocked on any map.

2. Cross-Mappin'
Description: Noble 1: Kill a player at long range with the DMR in a matchmade Slayer game.
Gamerscore Worth: 50G
How to Earn: This achievement can only be unlocked in Matchmaking within any competitive playlist that contains the Slayer game type. This achievement also requires the DMR weapon. The DMR weapon is usually the default weapon in Slayer, but can be found on any map. To unlock this achievement, you must kill an enemy using the DMR at a long range. You can tell if you're within the range when the reticule isn't red, but you're targeting the enemy. The kill doesn't need to be a headshot in order to count. The easiest playlist for this achievement is Big Team Battle, as there are more enemies, and you play on the bigger maps. This achievement can be unlocked on any map.

3. Offensive Driver
Description: Noble 1: Earn a kill in a matchmade Rocket Race game.
Gamerscore Worth: 20G
How to Earn: This achievement can only be unlocked in Matchmaking within the Multi Team playlist, as it is the only playlist with the Rocket Race game type. To get this achievement, you must simply earn a kill against an enemy. However, you can only harm an enemy when they're NOT within a vehicle, so you'll have to either forcefully eject them from the vehicle or wait until the driver flips the vehicle by accident. Once that happens, simply fire away at the enemy to get your kill and achievement. This achievement can be unlocked on any map.

Also, note that you must kill an enemy by either splattering them or with a Rocket Launcher within the passenger seat. Killing an enemy using the Rocket Turret on the back of the Warthog will not count.

Just before the vehicle hits, activate Armor Lock. If done properly, the vehicle should explode upon contact and you will get your achievement. The easiest playlist for this achievement is Big Team Battle, as there are more enemies and maps with vehicles on them.

5. Totally Worth It
Description: Noble 1: Earn a Double Kill from the Grave in multiplayer Matchmaking.
Gamerscore Worth: 50G
How to Earn: This achievement can only be unlocked in Matchmaking within any competitive playlist. This achievement requires you to earn a Double Kill medal (2 kills within 4 seconds of each other) by killing 2 enemies from Beyond the Grave (while waiting to respawn). This can prove rather difficult, so your best bet is to have a plasma grenade handy and get into a firefight with 2 enemies. Get them as close to each other as possible and let them take your shields and health away. When you're about to die, lob a plasma grenade into one of the enemies to stick him. Once you're dead and if you got them close enough together, the explosion will be enough to kill both enemies. This achievement can be rather difficult to do legitimately, so your best bet is to set up a boosting party and get the achievement that way. This achievement can be done on any map.

Due to a glitch, all three Defiant Achievements can currently be unlocked in Custom Games. See Candy From a Baby for more details.

2. Crackin' Skulls
Description: Defiant: Kill 3 players with the Oddball in a matchmade Oddball game.
Gamerscore Worth: 45G
How to Earn: Head into Matchmaking and find an Oddball game. The Rumble Pit and Team Objective playlists have Oddball gametypes, but I recommend Rumble Pit as there are more enemies to kill. Once you're in a game, pick up the Oddball and melee three opponents with it. To melee, press the button that Melee is assigned to on your control scheme (e.g. Right Bumper for Default, B for Recon, etc.). This achievement can be done on any map.

Due to a glitch, all 3 Defiant Achievements can currently be unlocked in Custom Games. See Candy From a Baby for more details.

3. Candy from a Baby
Description: Defiant: Capture two flags from an enemy capture zone in a matchmade Stockpile game.
Gamerscore Worth: 75G
How to Earn: Go into Matchmaking and find a Stockpile game. The Team Objective or Big Team playlists are best. Once you're in a game, wait for the opposite team to place a flag in their capture zone. Now, before the timer ticks to zero, take the flag within their capture zone, and place it within your team's capture zone. It doesn't matter how long you take as long as you don't drop the flag. Repeat this once more and the achievement is yours. This achievement can be done on any map.

Due to a glitch, all three Defiant Achievements can currently be unlocked in Custom Games. To do this glitch, you will need a boosting partner. Also, you must play each of the gametypes at least once in Matchmaking, or you can download the relevant gametypes [ Register or Signin to view external links. ] Once you have the gametypes, depending on what option you chose to get the gametypes, perform this following step:

Matchmaking - If you got the gametypes from Matchmaking, go into Custom Games, press "Game Type", go into your Temporary History and select the game type you want.

Download - If you downloaded the gametypes from the thread, do the same as Matchmaking, except select the game type section from the list and select the game type you downloaded. DO NOT SELECT THE DEFAULT GAME TYPE AT THE TOP OF THE LIST!

Choose any map, start the game and follow the guide.

4. Don't Touch That!
Description: Defiant: Prevented the attacking team from touching the flag in a matchmade 1-Flag CTF game.
Gamerscore Worth: 25G
How to Earn: 1-Flag CTF will almost always be on the "Condemned" map. With that said, you must prepare to play strong defense in order to prevent the enemy team from touching your flag. Use whatever you can - armor abilities, grenades, power weapons - to your advantage and do not stray too far from your flag, because this allows opportunity for the enemy to slip past you and simply touch the flag for even a second.

You must let the round's timer run out. If the enemy team has not touched the flag at all by the time the round is over, the achievement will unlock for everyone on the defending team.

5. Paper Beats Rock
Description: Defiant: Assassinated a player that just exited Armor-Lock in a matchmade game.
Gamerscore Worth: 15G
How to Earn: This is self-explanatory. You must play a match as you normally would, but when an enemy used the Armor-Lock, be ready to position yourself behind them. When they break free, try to assassinate them quickly before they can turn around.

6. All Alone
Description: Defiant: Was the last surviving uninfected player in a matchmade Infection game.
Gamerscore Worth: 10G
How to Earn: This achievement will also be obtained on the "Condemned" map. As a human player, you must survive the round until you are the last player standing. You are given a Magnum and Shotgun as a human, so be sure to use the pistol for long-ranged kills on the Infected, and the Shotgun during close quarter situations.

There are no clear hiding spots on this map, but the room you spawn in has a glass platform overlooking the rest of the room. Climb the stairs, and hang around up here. This is probably the best area to hold out during the match.

Price: $14.99 USD Achievements: 7 Gamerscore: 250

1. Top Shot
Description: Anniversary: Earned 3 headshots in a row in a matchmade game.
Gamerscore Worth: 50G
How to Earn: The DMR or Magnum will be necessary to pull this off. Simply score three headshot kills in a row without dying. Use the DMR's accuracy and range to your advantage by staying back behind cover while picking the enemies off from afar.

2. Emergency Room
Description: Anniversary: Infected 3 players in a single round in a matchmade Infection game.
Gamerscore Worth: 15G
How to Earn: Search for an Infected game in the new Anniversary playlist. As an Infected, you must kill three human players in the same round. The human players are armed with magnums and shotguns and can prove to be quite the threat. Try to sneak up on them or overwhelm them with a direct assault with multiple Infected teammates in order to score your three kills.

3. Stick it to the Man!
Description: Anniversary: Killed the flag carrier with a Plasma Grenade in a matchmade game.
Gamerscore Worth: 20G
How to Earn: As the description says, simply stick - with a Plasma Grenade - an enemy flag carrier during a Capture The Flag game. The flag carrier cannot defend themselves unless they drop the flag. Use this to your advantage and try to stick them while they're back is turned or before they decide to drop the flag.

4. Dive Bomber
Description: Anniversary: Performed a Beat Down on an enemy while using the Jetpack during a matchmade game.
Gamerscore Worth: 50G
How to Earn: When the match begins, choose the loadout that contains the Jetpack armor ability. It takes two beat downs from the front, and one from the back to kill an enemy. Thrust your Jetpack upwards, and while your are descending, aim to melee strike the enemy from behind. Do not hold the melee button, or you will accidentally assassinate them, voiding the achievement in the process.

5. License to Kill
Description: Anniversary: Ran over 5 people with a vehicle in a matchmade game
Gamerscore Worth: 15G
How to Earn: This achievement must be done on either the "Breakneck" or "Ridgeline" maps. The best vehicle to use would be the Ghost, as it has the boost-ability. Pilot the Ghost around the map during the match and aim to splatter 5 enemies before the game ends. To ensure all 5 kills register, try to use the same vehicle for the kills, meaning you will try to aim for a Splatter Spree while piloting the Ghost.

6. Bounty Hunter
Description: Anniversary: Captured 10 skulls at once in a matchmade Headhunter game.
Gamerscore Worth: 75G
How to Earn: In Headhunter, two teams are thrown against each other, with the goal of capturing skulls from the enemy team. Each player starts off with one skull. When you kill them, their skull will drop and you can pick it up. Once you have 2+ skulls in your possession, there will be a waypoint over your head that says how many you have.

If you kill an enemy who has 6 skulls on them, they will drop all 6. Simply round up 10 skulls and bring them to the marked "safe-zone" in order to score them. Scoring 10 skulls at once will end the game right away.

7. From Hell's Heart
Description: Anniversary: Killed an enemy with their own grenade that was stuck to you in a matchmade game.
Gamerscore Worth: 25G
How to Earn: This is a great achievement that can be extremely fun while trying to obtain. You will essentially have to allow yourself to get stuck by an enemy's Plasma Grenade. You will also need to hope that this enemy is very close to you, in order to sprint up to them, which will allow the explosion to kill you both. The achievement will unlock once you have both died from the same grenade.
