The notorious Battletoads level 3: Turbo Tunnel.
It’s not nearly a perfect run, but this is the first time I’ve ever been able to beat it. During this playthrough I lost lives in places I’ve never lost lives before. I also lost lives twice where I shouldn’t have, because I was celebrating over getting past what I consider to be the hardest part. I did a lot of internal screaming and audible groaning while I was trying to beat this level, but in the end I finally did it. For the first time in my life I get to see what comes after these darn speeder bikes.
I hope you enjoy this video, because it took everything I had.
