yeti.big

any ideas on how to open and extract? I want to pull the 3D maps so I can take screenshots

Anyone know how to open the .big files? 2.3gb

How to extract Yeti.big:

Download quickbms: search on google "QuickBMS - Luigi Auriemma"

Use this script and name it as name_goes_here.bms (Please note: i didn't write the following script):

# Yeti Engine YBIG (script 0.1.1)
# Ghost Recon Online
# script for QuickBMS http://quickbms.aluigi.org

print "when prompted, please type 'r' for automatically renaming the files with same name"
