How to Unlock All Levels

If you're comfortable with editing game files to use cheats, it's possible to start a new game with every level unlocked:

  1. Launch the game and create a new save profile.

  2. Close the game, then open Windows File Explorer and locate the file folder for Halo. Navigate to the checkpoints directory for the profile you just created (Halo > profile > All_Levels > checkpoints).

  3. Create a new text file in the checkpoints directory and enter the following: 

    0,0,0
    0,0,0
    0,0,0

  4. Save the text file as checkpoint0.sav.

  5. Create another text file named checkpoint1.sav in the same directory with the following text: 

    1,0,0
    0,0,0
    0,0,0

  6. Repeat the above step until you have 10 files total named checkpoint0.sav- checkpoint9.sav. For each file, change the first number in the code to unlock a different level. For example, to unlock the last level, enter: 

    9,0,0
    0,0,0
    0,0,0

  7. Launch Halo and load your save data to start the campaign with all levels unlocked.

Halo Easter Eggs for PC

Halo: Combat Evolved has a few secret Easter eggs that are just for fun.

Multiplayer Menu Secrets

From the title screen, select Multiplayer, then hover the mouse over the Gametypes option. There are two Easter eggs highlighted on the Master Chief's suit: The breastplate reads “All your bases are belong to us,” which is a reference to the NES game Zero Wing; and the thigh pad says “Sometimes I give myself the creeps/sometimes my mind plays tricks on me,” which is from the Green Day song Basket Case.

The Talking Grunt

After Echo 419 gets shot down in the final level, you'll come to a path with several tunnels. Take the right tunnel, then take another right at the first corridor you see. Here you'll find a talking grunt, but he doesn't have anything interesting to say.
