E-Gate

E-Gates are electronic portals invented by Professor E. Gadd that appear in Luigi's Mansion: Dark Moon. E-Gates first appear in the Secret Mine, but have a more prominent role in the Treacherous Mansion.

E-Gates are introduced in mission D-2: Hit Rock Bottom as a convenient way of traversing the Crossroads to reach the Skip Slope. Like many of E. Gadd's inventions in Luigi's Mansion: Dark Moon, E-Gates must be activated with a Strobulb flash. Only one gate must be activated for both sides of the portal to be used. When an E-Gate is activated, Luigi may transport himself between the two portals any time he is near one by pressing. Luigi can take objects that he has vacuumed with the Poltergust 5000 (such as balloons or buckets) through the E-Gate. This is necessary to completing the puzzles in the Treacherous Mansion.
