At this point, I reckoned I went too far in defense, even made a simple fail-safe to evacuate the city when things get bad (almost active totem near center).
At this point, I was kinda happy when my efforts to sabotage my of defense started to work, emitters at 311.7.
The defenses decided to really quickly fall apart... and the fail-safe failed, so three attempts to reclaim the totem via pausing,
massing a huge force of blasters and hoping they hold till the collector is done. Each try got harder to pull off but it was done by
mass drone concentration on one spot and a huge amount of suicide blasters.
Images seem to be really big (At least in preview), should I change to hyperlinks?
