Area Gate

"The orange has opened! Let us proceed to the next area!"

- Cap'n Cuttlefish after Agent 3 completed the first boss mission

Area Gate is a barrier in Octo Valley and Octo Canyon to block the player from advancing to the next area before all missions in the area are complete.

Description
Area Gates are wires with light bulbs, the outlet of the wire is attached to the Boss mission and gets discharged when the mission is complete. As a result, the light bulbs explode and the passage is cleared.

Trivia

 * In Octo Valley at area 4, there's an exploit to skip the area by painting the passage and jumping from the side of the Area Gate.
