Unseen Aperture :: What have you Seen?

Unseen Aperture: Series 1 Episode 4 :: What have you Seen? This is Episode Four, the long awaited FINAL Episode in Series One under the "Unseen Aperture" umbrella. I hope you enjoy it and comments are always appreciated. *The idea for the Unseen Aperture series was to create maps where the player would be rewarded for being extra observant. Then in the final episode in the series (this episode!), the player will be tested, if they have played the other episodes and seen what they needed to see, they will be able to complete the final episode's BONUS MAPS (!) for that series. I only ask that no one post cheats or solutions to the puzzles here in comments. Thanks. Special thanks must go out for the wicked amazing texture packs: PK01, PK02 by Philip Klevestav www.philipk.net Black Mesa Textures Pack 1, By Prototstar ...without them, it just wouldn't look this good!
