Recently, the developers of Warframe released a content update. Along with the launch of "Deeper Than the Vale", a new version of Oberon was introduced.
Now Oberon and his prime version have more armor (358 and 450 instead of 185 and 240), as well as updated effects and skills that should increase the survivability and power of the warframe.
You can add it to your collection until October 21st, and a Forma will also be given for logging into Warframe.
There are also full-fledged novelties, Digital Extremes has prepared the Nokko warframe, a new quest, and "Deeper Than the Vale offers so much "dispute" for research that it will be enough for an entire mushroom kingdom."
