It looks like the data after the header is xored with the byte 0x6b.
I'm not sure if the offset where the data starts to be encrypted is correct, but feel free to try this quickbms script for generating the decrypted file:

Code:

get NAME basename
string NAME   ".unityfs"

math OFFSET = 0x96
get SIZE asize
math SIZE - OFFSET

log NAME 0 OFFSET
append
filexor 0x6b
log NAME OFFSET SIZE
append
