Up to 2 more friends or additional profiles and as many controllers as needed.

Firstly, I am writing this as if you are just starting out (if you have already had a go don't worry, just carry on from where you are).

Now you must decide which leaderboard to go for first! I will use Solo for this guide (just switch it over to do team).

Select Solo Elimination (ranked) map etc is up to you.

Once the game has started, wait 30 seconds before getting your friend/secondary account to kill themselves, you must wait 30 seconds or more before the server will recognise the game officially.

Now continue this process till your main account is level 4 and your friends/secondary is level 1. This can take upto 4 hours.

Exit the game and check the solo leaderboards, scroll from your name up, if your account is the highest possible level 4 then skip the next step, if not.....

Go back into the game and repeat 10 more times, then check the leaderboards. Rinse and repeat until you are as close to the highest 4 as possible.

Now do not play again in solo until you have completed the next 2 steps, as the matches will not count, when you are beating someone 4 levels or more below you, you get next to no points.

Okay so you have reached your first goal of being 4 levels higher, now for the de-ranking. If you wish to Play it yourself it will take 4 hours or you can use a Sneaky trick and let the 360 do the work while you sleep/go to work etc!

Set up team elimination and then have your main account commit suicide until it is level 1 and your secondary is level 4 (Remember to wait 30 seconds before you do this!)

Set up team territory,type custom game,set to 1 base and respawns off,turn on helicopters,and set auto launch at 30 secs, the tag you wish to win must be controller 1, start the game and let the helicopter do the work.

Finally rinse and repeat the above steps and eventually solo will be yours.

For team just reverse the method and hey presto achievement unlocked!

Now if you are using more than 1 secondary account, when you de-rank in team, put all your extra accounts on 1 team so at the end you will have 2-3 level 4 accounts.

If you wish, you can run your solo game twice, taking your main account from a level 1 to a level 4. Then put it up against a level 4 again and you will have a main account level 6 your secondary account at level 2.

This is were having multiple accounts can get confusing, but if you can get your head around it then your quest, to be top of a leaderboard will be faster. Now at this point if you have followed my example you will have the following (based on 3 secondary accounts).

Take your level 2 play to win againt your level 1 making a level 4 and a level 1.

Play the 2 level fours together getting a level 6 and a level 2

Play the 2 level sixes together, your main account to win!

Then play the level 1 vs level 2 getting a Level 4 and Level 1.

Now de-rank your level 8 against your level 1 leaving you with:

Now play your main level 4 aginst another level 4 getting:

You can see the process required; rinse and repeat.

If you wish to get universal you will need 3-4 friends with 4 accounts each. You will need alot of co-ordination to get there, but it is worth it.

Follow the above steps but when each individuals main account is at level 8 get them to play aginst each other, this will give you two level 10 accounts and two level 6 accounts, you can see where this is going so rinse and repeat until you are the world number 1.

First of all make sure there are 5 gamer tags in the room. (1) doesn’t count. You can do this in Public Player, Private Player, System Link, or Ranked Matches as long as it is a Solo or Team game.

The original Maps are:

Boneyard
Nowhere
Temple
Treasury
Wharf
OldTown
Dry Dock
FishingVillage
Rocky Cove
Desert Gulch

Every game must have 5 gamertags in it to count. This must be done in Public Player. The original game types are as follows:

Solo Elimination: Bounty Hunter, Last Man Standing, Seek & Destroy, Sharpshooter, Thief

Win games of Co-op Elimination, Territory, and Objective 30 times. Ex: 15 wins Elimination, 12 wins Territory, 3 wins Objective. Each game you play must have 6 gamertags playing to count. It must be in Public Player, Private Player or System Link because there are no Ranked Co-op Matches.

This is a viral achievement that at this point is pretty widespread. Merely kill someone who has this achievement and you will have it also. If you are you having problems finding someone, post on the forums in the achievement trading thread.

See “Unyielding”. Do the same but don’t reload or use grenades. This can be done in Public Player, Private Player, Ranked or System Link as long as there are 5 gamertags in the room.
