Tips & Tricks for Echoes of the Abyss

Surviving your shift in Echoes of the Abyss requires excellent resource management. First, always stick to the paved paths when moving around the facility, as walking on them provides a significant speed boost. Second, don't wait for your power to drop dangerously low before checking the breaker. A sudden blackout triggers terrifying alarms, making it much harder to navigate. Finally, balance your sleep schedule carefully. Sleeping restores your energy but drains your hunger rapidly, so ensure you have enough credits for a meal before resting.
