The blue cube in Survive Overnight in a Mega Store sits directly behind the Weaponry section of the retail floor. Collecting this item alongside the other power blocks allows you to restore electricity to the store generator inside the electrical room.
Finding the Blue Cube Behind Weaponry
The blue cube spawns on the floor tucked behind the Weaponry department. While exploring the aisles during daytime hours, search around the weapon displays and shelving partitions until you spot the bright blue block outline. Daytime scavenging remains safe because store staff cannot damage you during the day cycle.
Carrying the blue cube requires one open inventory slot. If your backpack slots are occupied by weapons, Bloxy Colas, or burgers, drop a consumable item on the floor to pick up the cube. You can drop items at any point and return for them once the cube is safely relocated.
Transporting Cubes to the Electrical Room
Once you pick up the blue cube, bring it directly to the electrical room. The entrance to this maintenance space is secured until day three, when the repair chains come off the doorway. Inside the room, an electrical console features specific outlines designed to hold three separate power cubes.
Interacting with the blue outline mounts the cube into position. You must also retrieve the red cube location near the front checkout registers and the green cube from the Mechanic area to complete the set. Placing all three blocks initiates the charging sequence for the facility.
| Power Cube | Retail Spawn Area | Transport Route Priority |
|---|---|---|
| Blue Cube | Behind the Weaponry section | Carry directly to the electrical station |
| Red Cube | Near the entrance checkout counter | Retrieve while looting front store aisles |
| Green Cube | Mechanic department | Collect when passing intermediate store aisles |
Power Activation and Charging Times
The electrical unit inside the generator location requires a full day cycle to reach maximum capacity after you seat all three colored cubes. A progress meter displays the energy accumulation, shifting from red to yellow and finishing on green once the system charges completely.
Maintaining health and energy during the charging period requires regular food intake. Items like hot dogs, burgers, and Bloxy Cola prevent your sprint meter and stamina from dropping. Understanding how to turn on power before the night cycle starts gives your squad an advantage, because aggressive night employees attack the moment the lights go dark.
Unlocking Keycard Readers After Power Restoration
Fully charging the generator restores operational current to keycard scanners across the building. Card readers that previously flashed messages reading locked and requiring power will accept authentication once the meter turns green.
With electricity restored, you can utilize the manager keycard dropped by the store manager on night four. This grant of power allows access into restricted managerial offices and unlocks secondary routes needed to bypass retail security doors.
