Twilight CreationsZombies Third Edition Board Game

I tried my friend's 2nd edition game a long time ago, and I'm interested in buying the game for myself. What expansions would go with the 3rd edition?

What are all the expansions? Will they be released as 3rd edition or are 2nd edition expansions ok with 3rd edition base game?

Do i need the original game to play this ?

Can this game be played Solo?
