Awards are another feature of Halopedia. They are automated and are given after accomplishing a certain amount of various objectives. They are awarded automatically for two categories of activity on Halopedia.

  • Edits: Editing mainspace pages is recorded, regardless of the size of the edit. Awards for these are given for increments of 5, 25, 50, 100, 250, 500, 750, 1,000, 2,000, 3,000, 4,000, 5,000, and 8,000 total page edits. No edits of any kind on pages other than mainspace count toward this number.
