LVL 43, and feeling a little disheartened.

I've been absolutely loving the game, and I've got to a stage where I feel I should use the vapour condenser, and I've been watching videos and they're getting waves of ludicrous animals attacking them.

I guess combat and the stress of waves just isn't my sort of thing. I was kinda hoping that I could just wait till I was at a high enough level and defending it would be routine and easy?

I haven't tried concrete yet, is that animal proof? Do I really have to build a big fortified base or should I just give up on the whole vapour thing and just explore the rest of the map and get exotics from caves??

I really don't want to give up as I'm having so much fun, but if those are critical to the game, that's a shame...
