List of classic levels?

Does anyone have a list of what classic maps are listed as secrets? And is there any way to unlock them without manually finding all the secrets?

hardcore gamer unlock them all by finding them

It's a shame the "Dis" level wasn't available as a classic level, it would've been cool to fight the new spider mastermind the classic way just like the Cyber demon.

I'd like to know why Gotchya isn't one of the levels, talk about a missed opportunity to pit them against each other.

I know it would be ridiculous but I wish Sandy City was in it haha, it would be awesome

I agree. It'd be cool to fight it in a big arena.

Maybe E4M8 would have been better for that, since it's more of a 'complete' level and also has the Mastermind in it.
