Call of Duty: Infinite Warfare features several hidden Easter eggs and a comprehensive list of achievements/trophies to unlock. Many achievements are tied to completing the campaign on various difficulties, collecting all SDF Intel, or completing all side missions. However, some are more unique and require specific actions or discoveries.

- 'The Longest Day': Collect all 30 SDF Intel data pads. Refer to the 'Collectibles: SDF Intel' section for more details.
- 'Dominion': Complete all Ship Assault and Jackal Strike side missions. These are accessed from the Retribution's bridge.
- 'Gun Nut': Scan 10 weapons for the first time. Simply pick up and use 10 different weapon types throughout the campaign.
- 'You Know Nothing': Kill a C6 robot with a melee attack. This is challenging but doable; weaken it significantly first.
- 'Gravity Kills': Kill 10 enemies with environmental hazards in zero-G. Look for explosive barrels or exposed pipes.
Keep an eye out for subtle nods to other Call of Duty titles or pop culture references. Exploring off the beaten path can sometimes lead to unexpected discoveries. For a complete list of achievements and detailed guides on how to unlock them, consult an external achievement tracker or a dedicated guide.
