Campaign Complete: Normal (Halo 3 achievement)

Campaign Complete: Normal is a Halo 3 Campaign Achievement.

It is earned when the player completes the Halo 3 Campaign on the Normal difficulty. This Achievement gives 125 Gamerpoints to the player. It can be earned through either co-op or single player, or a combination of the two. If a player completes the Halo 3 campaign on the Heroic or Legendary difficulty without this achievement already earned, they will be unlocked together.

It is represented by a shield with the Marathon symbol and one Combat Knife across it; the same as the normal difficulty symbol.

This achievement unlocks the EVA Armor Helmet for SPARTANs in multiplayer.
