The vault is a dome-shaped building that was conceived by the first expedition. Its purpose was to offer protection to a new type of advanced bot. To protect it from insect attacks, the vault was locked by 4 keys. Only after you find the 4 keys and place each one of them on their corresponding slots will you be given access to the bot.
The keys are the four items required to open the vault. They come in four varieties, all of which must be collected to open the vault:
- Key A: Blue and triangle-shaped
- Key B: Red and pentagon-shaped
- Key C: Green and shaped like a six-pointed star
- Key D: Yellow and circularBuildings
