feel free to add me on uplay too, spronk69
i added everyone else who posted theirs so far. yeah you can do the amazon buy, get beta key, cancel trick if you really want but really it should be easy to get an invite from someone here already, every person in the beta can invite 3 other people but you have to be friends on uPlay. also everyone is streaming it so you can tell quickly if you'll like the game or not. invite codes are universal so you could send one to a friend on PS4 and they can play on PC I believe.
i'm not playing this weekend but i'll be playing at launch, bought a $20 AMD rewards key (that also gave DMC5) so easy launch play on PC. keep in mind the gold edition gives you 3 day early access, normal noobs like me only get in on regular launch day
