An upgrade from Nexus FEC with some new hardware and pack alterations as well as software and firmware alterations. The standard LCDs, similar to those in the Infusion packs were scrapped from Nexus FEC and replaced with a brand new coloured LCD display. Many other features have altered including the shoulders sensors with built in speakers. As for looks there is not really much difference between both version, with the exception of the shoulders which had speakers placed within them and the Nexus logo removed from inside.
