So basically, I've just fired the game up for the first time in, at a guess, 2 years or so, aaaaand basically everything has changed and it's a bit confusing.
Everything looks different, a third of my mechs are invalid, all my skills and stuff are gone, I've been refunded a load of I don't even know what, there's a crap-ton of new equipment (and mechs, but I kind of expected that) and something called Solaris is plastered everywhere I look...
Can anyone give me a nice digestable, abridged idiot's guide to what the hell has happened? For reference, I think the last time I played was right around the time factions wars released.
Inb4 "read the patch notes" (which I got last time I tried this, only to find the game was borked at the time anyway so left it alone), I seriously don't have the time or inclination to read two years worth of patch notes!!
Thanks in advance!

P.S. I didn't leave because I was salty about the game, just kinda burnt out on it.
