SNAKE BOSS from Dark City Part 1 by Nina Croft

Description
With the permission of the level builder, I release the WAD from Dark City Part 1 by Milan Penčić Lima, for the LAST level (Broken Bridge).
You'll get the SNAKE BOSS in this WAD.

Here's how to set up the boss:

Plant 0 is the body of the Snake
Plant 1 is the tail of the Snake
Mutant is the Snake.
Plant 5 is the destroyed Snake.
Bubbles are the fire the Snake spits and throws at Lara.

1) Place Plant 0, 1 and 5 in the room. Plant 5 won't be visible when you place the Mutant onto it.
2) Place the Mutant onto these static objects. Trigger it normally.
NOTE: You need the BUBBLES in your WAD as well! Don't forget to add this object to your WAD!

If you want to kill it as Lima did in Dark City 1, place the Rolling Ball (Bus) above the Snake's head.
Use the Chain (untriggered) and Shatter 1 to "fix" the Bus in place. When Lara shoots and destroys Shatter 1, both the Chain and the Bus are triggered. The Chain will start to swing, and the Bus will fall onto the Snake and kill it.

Instructions for the shatter EGG:
Just place Plant 2 and Shatter 0 onto the same square. You don't have to make Plant 2 invisible, it's a bit smaller than Shatter 0 and it won't be visible. Place an enemy inside Shatter 0. You can place Small Beatles, or a snake (included here as Crocodile). When Lara breaks the egg, Plant 2 will remain as a broken egg.

Two statics also included: Concrete pillar (Plant 3) and metal fence (Plant 4)

Credits to Lima, please!
