Trailer items may include:

Weapons: Basic offensive and defensive equipments. Consists of blades, projectiles and firearms. Most accessable via PUE (purchase/unlock/equip). Some must be unlocked by completing challenges and side missions. Others mandatorily unlocked throughout campaign stories.

Outfits/Armor Sets: Increase the protagonist's maximum health and damage reduction levels. Armor may be purchased or unlocked. Specific outfits and armor sets must be unlocked via campaign missions. Customizable armor can be upgradable by collecting upgrade plans located throughout the city. Only one set of unbreakable armor.

Mission Items: Could be high-powered offensive or defensive weaponry, collectable souvenirs, mementos, or salvaged pieces for trophies. Only weaponry items are wieldables.

Codex: Allows the protagonist to view the records of the ancestors about various wesen types. Updated records are available only after first encounters.

The Grimm Diary: Separated from the Codex, this specific diary allows the protagonist to record the overall progress (AKA save game). Not necessarily the only saving spot (trying to avoid GTA save game nightmare), but built as a secondary saving spot for those who wish to save their stories in style.

Rare Potion Storage: Allows the protagonist to temporarily infuse the weapon with designated potions and poisons in order to take down specific enemies.

Mixture: Once the protagonist collects enough scattered city items for upgrade plans, the Mixture will be the place to research the upgrades.

Archival Film Footages: Allows the protagonist to view the ancient Grimms and their time of days. Most of the AFF are available by completing side missions. Specific AFF are mission footages that are interactive (AKA the protagonist will be switched to a Grimm ancestor and walk through the entire ancient times level) and will be unlocked once the level is complete.

Trophies: Obtainable by completing missions, assignments, challenges, unlockables, etc. Need more explanations?

So far I can only come up with these. Anything else I missed?
