Чужой (Alien)

Task: 5.8 MB DOCX (OOXML/ZIP) pseudo-scientific paper about the Alien franchise, flag hidden somewhere inside. Solution: the flag was split across per-entry ZIP central-directory comments; concatenating each entry's comment and base64-decoding yields the flag — invisible to Office and image/text stego tools.
