Bought this the other day and was about to submit to OzBargain but it had sold out! Looks like they have stock again.
This limited edition pack features:
The Explosive Mission Pack features an entirely new mission with a special cameo appearance from one of the original DEUS EX characters, plus the Automatic Unlocking Device, the M-28 Utility Remote-Detonated Explosive Device (UR-DED) and the Linebacker G-87 multiple shot grenade launcher.
Ozgameshop is a great site.
