play the game level to level going through and it will unlock new levels.
or you could get someone that has all levels and get them to invite you to play a level you dont have and it will be unlocked for you.
Only way is to hack it:
1. From Halo, select Profiles and create a new profile
2. From Windows, locate the 'checkpoints' directory for the newly created profile. You will find this in the My Documents folder,
eg
D:\Documents and Settings\...\My Documents\My Games\Halo\savegames\All_Levels\checkpoints
3. In this directory create a text file called checkpoint0.sav with the following text
0,0,0
0,0,0
0,0,0
4. Repeat the previous step until you have 10 files named checkpoint0.sav ... checkpoint9.sav
and for each file change the first number on the first line to indicate the level ie
0 The Pillar of Autumn
1 Halo
2 The Truth and Reconciliation
3 The Silent Cartographer
4 Assault on the Control Room
5 343 Guilty Spark
6 The Library
7 Two Betrayals
8 Keyes
9 The Maw
eg for 'The Maw' level you will have a file called checkpoint9.sav with the following text:
9,0,0
0,0,0
0,0,0
5. From Halo, select Campaign and Load Game. You should now have access to all the main game levels.
You dont 'unlock' it, you BUY it, then enter the activation code in the case.
If its not one of the original maps just download it under one of the Halo 2 DLCs you should be able to find it if you look hard enough.
