Secrets for Icarus: Alien Vanguard

list by Jim Kennedy, complete as of Dec 1, 1997

- Use the Automap (TAB key) to see which direction you are going.
This secrets list refers to compass directions (i.e. N, S, E, W, SW, etc.)
Looking at the Automap, these are the directions for any Doom 2 map:

- When I tell you to run, I mean hold down the SHIFT key while moving forward. Some secrets are "running puzzles" and require you to run to get it.

- We worked hard to "hide" secret or unimportant lines in Icarus, so follow these directions as close as possible since many secrets include secret, hidden lines and trip wires.

- There is no way to see a "Sector" number in the game, you must use a Doom 2 editor (e.g. DETH). A sector is an area (e.g. one or more rooms, a post, a door, a doorway, ...).

- "Texture" is the sort of wallpaper you see on all walls, floors and ceilings. Its the technical term for graphics used in the game.

--- Useful information about this level:

Hint #1 - Not marked as a secret, this gets you the blue key. From secret #253, go east down lift past blood fountain, then stop at east most wall (use automap), there is an invisible trip wire just south of you, it runs from where the west wall sticks out across to the east wall.
   This is a running trick, so keep that trip wire in mind, from there you need to run (hold shift key down) into the south room (star on floor in automap, green marble floor), run up the steps into the now dropped down blood bath, heading south into the hidden transporter at the bottom. This is a hard running puzzle, the blood bath (lift) will want to rise up and you only have a short time to get in that small room.
   After transporting, the blue key is here and the blue door is to the west.
