Dozens of Dee Dee duplicates are destroying the Lab! Capture them before it's too late! What a disaster! Dee Dee has activated the Duplication Machine and now hordes of dangerous Dee Dee clones have invaded Dexter's Lab! Suit up with the Dexter Vector Dee Dee Detector and protect the Lab at all costs! Instructions: The game takes place in a Virtual Reality view of Dexter's lab. Use the mouse to move around and when you see a Dee Dee duplicate, hit the mouse button to fire. Remember to watch your Protronic Fusion Energy Gauge - if it runs down to zero, all of the Dee Dees will be set free and you'll have to start at the beginning again. There are 4 levels full of Dee Dees. When you clear a level, you move on to the next one. When you have cleared the final 4th level, it all comes down to just you and the REAL Dee Dee. Find her and touch her to win the game. Now get going. Dexter's counting on you!
