[Stage] STM's Challenge Stage v1.51

[STM1993]

Looking for a new Stage mode that is interesting yet challenging, and not another army vs army fight? Well look no further!

What is this Stage about?
* I wanted to make a new interesting, yet challenging stage mode by modifying ONLY stage.dat.
* This is because I felt the original stage mode relied too much on an army, plus the gameplay felt repetitive and is not generous with milk.
* In the main stage, weaker enemies have more HP now and are more densely packed in a smaller space in greater variety.
* To compensate, the end bosses have much less HP so they don't feel like damage sponges.
* Conversely, allies are way fewer in numbers and have way less HP.
* In survival, all enemies have less HP to speed up the gameplay and make it less tedious.
* Slightly modified etc.bmp & etc_mirror.bmp are provided so that the messages don't look weird when they appear in the stage.
* Included mainoriginal.wma, which is the same as main.wma, because I understand people may not like menu music.

Pastebin if you only want to look at the data.

I would post some screenshots, but they won't do the stage justice. Here are some videos from when I was testing the stages instead:
Stage 1 is meant to be a tutorial, but its by no means a cake walk.
Stage 2 introduces heroes & some stronger minions.
Stage 3 is the standard.
Stage 4 expect very high damage ambushes.
Stage 5 is very tough, especially 5-7. Might need to patch this in future.

Survival is the same as original LF2, but with the following changes:
* Start at wave 11 instead of wave 0.
* Before the Survival officially begins, you have access to an armory and can choose to save an optional 150hp Jan ally (with ten thousand +1 reserves).
Don't worry about the excessive reserves, if all the players die, the reserves will be disabled anyway.

History:
After some time, I decided to go back and remake my old custom stage. I ended up revamping the stage so much that it pretty much no longer resembles the old one, and fixed any crashing issues that plagued the old stage, so I decided to make a whole new thread instead.

Enjoy!

Bump because I've given it a huge update.
* Balancing adjustments, especially to Stage 3 & 4. Also adjusted ratios greatly.
* All stages have 6 substages in total (stage 5 has 7 as before).
* Completely new Survival added.

Don't have an up-to-date video playthrough of it, unlikely to have time to make one because I'm busy.
See first post, added a video.
Survival playthrough will come another day.

I've scripted up an image - a storyboard, if you will - showing everything that spawns. Check it out:

I also generated the storyboard for the stock stage.dat, here.

Script attached in case it's useful to anyone.
