give us the old tower defense scenario back please

[FritzHugo3]

The new scenario for tower defense - it is not a tower defense scenario!
So let the new there but please give us the old back too.

I have never understand why you deleted the scripted scenario with the 20 waves. it was so cool and i like to have more than one of this challances.
it is nice for speedruns and as a be beter and beter challance. I misse this in the new Factorio versions. And always go back in Version only to play this its not comftable.
