My local board game shop sells Nemesis lockdown and I'm trying to decide if I should buy it or not. The game looks awesome, however, it's a little pricey.

Heard some people state that lockdown was a little harder to learn, and then they'd recommend newer players learn the original prior to getting the lockdown version.

I did have a few other questions about it though. Do the expansions work with lockdown? Is there any additional player expansions that you can add on to it? We have a gaming group regularly with 5 to 7 people, it'd be really nice if we could fit those additional two people on.
