Highlight to read:

-For the godrays use additive render mode and set the alpha value to something around 10-15, it looks much softer and realistic that way. You can even set the color to match your envlight, but darken the values to something very close to black or it won´t look well.

- Use a palid color fog to attenuate the darkness. Relatively thick fog will give depth to dark areas. If you are worried about the exteriors looking ugly with the fog you can use triggers to alter its value.

-When the elevator goes down in the combine compound, soldiers will run at you giving you no time or room to fight them, but then their bodies will clip the elevator´s floor.

- The RPG is given to you in the middle of a tough firefight, I personally used it to kill the elite combines and then had no ammo to take down the gunship. I saw a crate of missiles at the bottom of the catwalk, but i had not enough healthh to make the fall. This killed progress as I couldnt do anything else. I suggest you to either move the crate upstairs or make the door where the RPG was openable and make a path to where the crate is.

Highlight to read:

- the barnacle sewer area felt very hard to navigate, almost frustrating, constantly stopping for barnacles and sliding off the pipes
- press door button => receive rpg? that was weird
- wasn't certain I had to backtrack (didn't see the way down at the balcony), felt lost
- backtracked fired rockets at gunship, ran out of ammo, got killed
- eventually noticed I could jump over the railing, received damage while allready on low health :/
- after the jump you throw more combines at me, the prior fight was allready pretty brutal, I could have used an oppertunity to restock on health and ammo
- got killed various times by the machine gunner due to low health, kept backtracking to the rpg crate and eventually killed them all
- jumped over the trainwreck and got stuck (barrel at lambda sign)
- invisible wall at the end breaks immersion, better to fade it out a little sooner?
