Design for an artillery outpost that does reasonably well with the updated biter pathfinding.
- Outer walls (maze / dragon teeth) distract biters so they get incinerated efficiently
- Outer walls are placed outside of roboport range to prevent silly robots flying to their death. Mostly.
- 3 stations:
- passenger station
- supplies loading (walls, repair packs, lasers, bots) with 4 "maintenance" artillery turrets fed from an artillery train trailing the supplies wagon
- artillery train station with room for lots of turrets for "initial clearing"
Vulnerability is the rail and power supply coming in. To really solve the power issue I would have to switch to gun turrets and something like steam brought in by the supply train, but that's too much of a hassle. So, I would advice making sure the rear is guarded, either by your main base or by another outpost (I build them in pairs, one N and one S, to continue expanding to the W or E.
