Hey all! I just started playing Boom Beach today, and although I've read all the links in the sidebar, I wanted to ask a few more questions, and would be grateful if you could answer them for me.

I play Clash (currently a beginner TH8) so most of my questions will be based off that.

1. Can you only ever build one thing at a time?

2. I read in the beginners guide that it's okay to upgrade your HQ before maxing out your base. Coming from Clash, that scares me. Is it true?

3. What are Task Forces like? Do they engage in battle with other Task Forces or do something like missions together?

4. What should I upgrade first? Defense buildings or resource buildings?

Once again, thanks for any help!
