You will not see much difference then chapter3 but there are new and very well hidden inventions in this chapter.
chapter 5:
short cinimatic
chapter 6:
New scenario, new quest, new inventions, new enemies.
Hints:
There is a spellbook hidden in chapter 6.
Think about your health.
You can buy tools in chapter6.
If you didn\'t play chapter 1-3, you better do them first.
Use your camouflage ability enough.
Helmets and guns have a weapon or armor-racket as model so look out.
There are some items that look like doodad so look very closely.
Tell me about bugs, inventions, tools and comment.
Enjoy the game.
