You may like it. Most of the unlocks are missions (non combat). Oden can be unlocked exclusively by mission rewards. It's not too onorous and I enjoyed all of it. Best path to an end engineer by a long distance.Admittedly, I haven't unlocked any of the suit engineers, know how to unlock them, or have dabbled much in bipedal leg-based content. Besides the odd walk through the concourse in search of G3 suits.
I've been lucky, I had nv from a premium dominator G2 I got in the first week but I've been desperate to get it for my mav too. If not for the >1 week where Hero Ferrari's unlock task was written incorrectly, I'd have gotten to oden over a week ago.
Not too shabby.
Just upgraded tonight. And now I never need to get it again. 2 weeks play. Just not an issue.
