A new enemy: the Centipede. As the outpost grows, eggs can hatch a larger beast instead of a spider. It is tougher, hits harder, and strikes several neighboring cells at once — walls, wires, buildings, and units. Nearby spiders join the raid. It does not appear at the start; the colony has to grow first.
Off-screen attacks no longer vanish. A damaged building outside the camera shows a colored edge arrow (yellow → orange → red as HP drops). Click it to jump the camera there. Walls and wires are not marked.
Smarter targeting. Creatures no longer take long detours to a distant turret when a building, wall, or wire is already next to them. Wires are valid targets. Guards are still preferred over workers; turrets still matter if they are close enough.
Plants. Thick growth in one cell no longer stacks into endless HP, so burning and clearing dense patches is more predictable.
Other: fallen creatures linger and fade instead of vanishing; wall and animation glitches are fixed.
