RacingFreak | Smuggler's Run - Leftover Development/Test Levels @RacingFreak | Uploaded August 2021 | Updated October 2024, 1 day ago.
Last year I uploaded a video exploring two test levels. Since then, I've managed to fix the audio issues and find two more levels! However, as it turns out drew and test2 are essentially the same.

The now outdated video (featuring only BillTest and test) can be found here: youtu.be/us2_F2T7fNQ
