LEVEL 25

Well... We're here, solver...

Seems like we need 6 symbols to proceed past this point. Each symbol requires something you've learned from me throughout the past. It's time to show what you know. GOOD. LUCK.

1. eraciputalitno (reverse in pairs of two)

2. Back to where it all began... Not the lobby, of course.

3. The source of the problem.

4. You've seen this one before. 01100001011100110111010001110010011011110110111001101111011011010110100101100011011000010110110000101110011010000111010001101101

5. Maybe there's some kind of mistake in the image...

6. Oscar Bravo Lima India Tango Echo Romeo Alfa Tango India Oscar November Delta Oscar Tango Tango X-Ray Tango

7. Once you've obtained every symbol, add a .mp3 along with the site that's been used for the audio. Then, we'll finally make it into the void.
