This article is about Tech Square in the future. For the past version see Tech Square.
Tech Square is the first place you enter after Dexter accidentally sends you too far into the future, and serves as the game's tutorial. When you land there, you notice that parts of the Time Machine are scattered everywhere, showing that it was destroyed on your arrival. The area's infected zone holds Fusion Buttercup's Lair, and it's your mission to enter her lair, defeat her, and rescue Dexter. Near the end of the tutorial, Tech Square becomes completely submerged into the fusion matter sea. You barely escape along with Numbuh Two, Samurai Jack, Buttercup, and Numbuh Five.
