Quick notes

Use power-ups for a planned encounter. A timed boost is most useful when the route ahead contains a meaningful threat.
Match equipment to the hazard. The Rebreather supports underwater travel, while the Environment Suit addresses environmental danger.
Keep cells for powered protection. Power Screen and Power Shield use cells when protecting the player.
Read the inventory before the next arena. Some useful items are stored until activated.

Match equipment to the hazard

Equipment checks

Useful tip

Some useful items are stored until activated. Review what is available before a boss or difficult room instead of forgetting the equipment while relying only on the currently held gun.
