They will be undergoing changes concerning the special powers (New and upgraded ones), the hero powers (such as Thor's), the use of exoskeletons, drones, satellites and several upgrades, as well as bug fixes and unit balance.
You will be able to find these new features in a version of the mod that should go live mid-December. The update will also include the new Stargate mechanism, the improved missions and WorldBuilder, as well as a few other smaller additions such as the Goa'uld scaffoldings.
Nice :)
Sounds awesome, love the Asgard and wish we could've learned more about them on the show.
Though, I suppose we learned what was pertinent to Earth atleast.
