And Micheal Ironside is back! They're also finally implementing AI teammate customization (long overdue) and there's gonna be a ghost pack including the SC-4000 assault rifle and FN Five-seveN from Blacklist, AN/PVS-21 and GPNVG-18 NVGs with flip up/down animations and their own night vision filter, another Splinter Cell outfit, Splinter Cell "Echelon" gloves, karambit knife melee takedowns (activated by wearing either the outfit or gloves), and some weapon camos.
Challenge rewards include Sam's tri-focal NVGs, new proximity mines, and a patch.
