The wiki contains information about each round for BTD5 and BTD6 but I can't find anything for BTD4 (or any other predecessor). The rounds are very similar to BTD5 but there are some important differences. I lost the first challenge once because I was not prepared for the Lead's on round 42.
Is there a list somewhere to be found? If not, is there an easier way get the information than actually count or recreate from RBE and observation?
Btw, I'd be willing to add it to the wiki if I can get the information required.
