The Axion Plains demo was very short, and very curated. Can only play Nell, Ult Freyna, or Ult Bunny. All the specific setups that you can tweak a bit, but the gear / cores are custom made, so not what we'll be using. It is exactly what was shown during the Dev Stream awhile go, one mission and a partial encounter with Wall Crasher.
I used Freyna and didn't bother with Nell as there was no option to build her how I plan too on release. The mission was pretty good, imo, very hectic and the new Elite mobs were a good addition. Nothing really game changing, and the new dmg resistance mechanic didn't feel obnoxious. The hoverbike was alright, I think its size is scaled up too much though. The zone itself, or what we had access to was very plain, no hills or canyons. I do hope that the full zone is very active with a nice variety of missions (I fear it wont' be though).
