- The Health Flask is the first item that must be unlocked at the Collector in order to begin unlocking other equipment and upgrades.
- Multiple Mutations found within the game change the properties of the Health Flask in some way. Extended Healing, for example, extends the duration of the regeneration effect given by the Health Flask to 15 seconds, while healing 85% of your health instead of 60%, and also providing the player with a damage buff during this time.
