The Museum is a kind of archive which tracks completion progress for Weapons, Enemies, Items, Cutscenes, Data Logs, Secrets and map completion as well as having player stats. Unlocking entries allows access to additional information to said entry: Weapons show their base stats and Enemies can be viewed as a 3D model.
The requirements for entries vary from category to category:
- Weapons need 230 kills per Weapon to unlock their cards, alternatively, cards can be purchased from Leonardo Brushido for 10 Wrenches each.
- Enemies have a chance to drop their card upon being defeated, with Bosses being guaranteed to award the player their card upon first defeat. Alternatively, cards can be purchased from Leonardo Brushido for 10 Wrenches each.
- Items get their entry upon first collection.
- Gadgets get their entry upon collection.
- Cutscenes get their entry upon being shown.
- Data Logs get their entry upon collection.
- Map completion is tracked via two factors:
- Has the map been completed?
- Has every Data Log and Secret been unlocked?
Weapons which have been used but have not achieved the required 230 kills will show up as well, but their entry will be greyed out. Same goes for Enemies which have been encountered but whose cards have not been picked up.
