Secret Levels, or Secret TVs are hidden levels that can only be found in Gex 3: Deep Cover Gecko. The object of each is to collect 50 Fly Coins within the time limit. There are four in total, and each takes you to a unique level in the game:
- Dial "A" for Arson/Peg Leg Polka (Mission Control)
- Braveheartless/Temple of Gloom (Lake Flaccid)
- The Abyssmal (Slappy Valley)
- Cheesy Rider (Funky Town)
After collecting 50 fly coins then Gex would have to find the vault key for that level. A skull, a shield, a star, and a radiation symbol.
