Easy

"Your foes cower and fall before your unstoppable onslaught, yet final victory will leave you wanting more."

- Description from Halo: Combat Evolved and Halo 2.

"Laugh as helpless victims flee in terror from their inevitable slaughter. The game basically plays itself."

- Description from Halo 3 and Halo 3: ODST.

Easy is the least challenging difficulty setting on Halo: Combat Evolved, 2, 3, Halo 3: ODST and Halo Wars. The enemies are few, target inaccurately, and are overall far weaker than on higher difficulty levels. Many players use it to learn the story. After they accomplish it on easy, they will often play again on harder difficulties.

Summary
The icon for the Easy difficulty setting is represented with a shield that has the Marathon logo encrusted into the center. This is for people just beginning to enter the Halo Universe and the first person shooter genre.

Among the features the player enjoys in easy mode are:
 * A tougher health meter.
 * Shields being at 200% their "Normal" capacity.
 * Lower health and shield levels for enemies.
 * Elites or Brutes being less common, and there are very few Major Elites or Brute Captains. Minor Elites or Brute Minors are almost exclusively seen.
 * Less intelligence for enemies and tactical action. Enemies are far more reckless and easy to kill.
 * Marines and other allies being tougher, more accurate, and doing more damage.

Trivia

 * Most of the achievements in the Halo series do not unlock when played on Easy as most need to be on Normal or higher though there are exceptions. In addition, no skulls will appear in Halo 3 when played on Easy difficulty except for the mythic skull, however the achievement for finding it will not be earned.
 * Developers have referred to Easy in Halo: CE as "grandma mode", according to the official guidebook.
 * 343 Guilty Spark will suggests the player to switch to "Easy" if the player negatively contribute by killing off allies in Halo 3 with the IWHBYD Skull on.
 * In the beginning of each of the Halo games, you will have to do the basic procedure to check the Player's control scheme for Easy and Normal, whilst in Heroic and Legendary, you will skip them due to the assumption that you will be already familiar with them.
