I started off with a larger than normal safe zone in 0.7.1 and managed trough careful pollution to avoid creeper expanding near my area and to avoid triggering an attack

now I need to expand more to get more iron, and I am about to get close with pollution to one of the nearest bases

the fact is, I had never had an attack since the newer version so I have no idea what to expect or how to gauge defence effectiveness.

is something like this able to stop a starting wave? Those are 5 lasers.
what decide how big the enemy will be, just the average pollution over their spawner?

Thats more than enought for the first wave.
The first wave is easy, only small biters the problem is when there are bigger biters.

Yeah, that'll be plenty of defense for a long while. You may want to double up on wall thickness for the top and bottom though. Big (and maybe even medium) biters can attack over single-thickness walls and chew your turrets.

8 turrets surrounded by a 2-layer wall were plenty for me until 15 hours in or so.

I use 12 turrets (with some damage and firing speed upgrades) surrounded by a 3-layer wall now for my mini-bases and they easily take down many waves of big biters without needing repairs 25+ hours in.


The trick is to connect multiple power lines to your little forts so they don't loose power when the biters inevitably chew down a pole or two.
