I’ve been using a single turret and some walls to defend my base against wandering hordes and zombears and such, most of my time (several months worth) after acquiring enhanced memory banks has been spent training my cutting and melee skills, using my diamond katana I can slice apart almost anything in a single blow.
I recently acquired a scabbard, which is actually quite useful, as I can sheathe my weapon in a fraction of a turn, and pull it back out very quickly (I move barrels and such around in combat quite a lot), but apparently you can also perform an attack while drawing your sword out (What was that called again?)
I learned this by accidentally cleaving apart my turret instantly after I’d come back from a looting run, naturally it exploded directly in my face and just about killed me.
The explosion attracted a pack of zolfs, several zombears, and a mi-go, I think I’m going to just leave this base to them and go somewhere else…
