Bottles are a type of unlockable that varies between a gold and a blue bottle. Collecting all the blue bottles in a chapter will unlock character profiles relating to said chapter, while gold bottles unlock concept art. These bottles are overtly visible, easily found with the help of Shrink Sense directions, or more subtly hidden. There are eighty-three bottles in total.
The bottles all have similar features: glass vials with cork stoppers and a thin label tied around the neck, bearing the name "Alice" and the symbol of Omega. The only difference is that some bottles are gold and others are blue.
- During a second playthrough, to help the player, previously collected bottles will cease to glow as they originally did. This signals that the bottle has already been collected and that there is no need to collect it again.
