Sorry to talk like this, but CAN SOMEONE TELL ME WHERE TO FIND THE FIFTH F***ING KEY IN THIS STAGE?
I got 4 of them. I found one of them in second "light speed thing path" (where you see the fire walls for the first time). SPOILER> The key was in the beginnings of the path on the right side. Another key that I found was SPOILER> When you play the dark mission und jump into the last search light. From there, you can reach a higher place, where you find another key. Unfortunately, I don"t remember where I found the other two keys. But the one that is left must be a VERY VERY VERY hard to find one! I tried everything I could think of, but I just had to give up after some hours!
Is there someone who can help me? Thanks alot in Advance!

The keys you've mentioned are keys 1 and 5. Here are the locations of the other 3. (I have the guide on gamefaqs on in another window as a reference.)
Key 2: After the first section with fire walls, fall down to the platform underneath the three GUN drones. There is a ? thing next to it.
Key 3: After check point 4, there should be a vertical shaft with a bunch of lights moving upward. Get on the left side of the right pole.
Key 4: During the section with a series of spot lights, you will run into a part with 2 drones. Fall down to the platform nearby.

Thank you very much! It was the 3rd Key that I didn"t have. I even looked around at that part before, but I somehow didn"t see it.
