380-metre wild island. Gather, drive, portal.
Open Country is the biggest scene in Sheep Dog Sim — more than four times the area of Rolling Hills. Wider, wilder, with denser tree clusters and a heightfield that drops to a long shoreline on the north edge. There's no corral here. The objective is something else.
On the north shore stands a magical portal — a ring of standing stones wrapped in slow blue light. To score, you have to push sheep through it. But the sheep don't know what the portal is, and they don't want to walk into the water-edge cliff that flanks it. So the round happens in two stages.
Stage one: gather. A round-up zone appears somewhere on the island. Hold the flock inside it for two seconds. The flock counter ticks up to lock in your gathered count.
Stage two: drive. The portal activates. Now you have to move the locked-in flock north, across whatever terrain stands between the round-up zone and the shore — usually a ridge or two and some tree cover — and through the stones. Sheep that cross score; sheep that don't, don't. The clock keeps running through both stages.
Rolling Hills is about steady-state pressure: keep the flock together, keep them moving toward one corral. Open Country is about transitions. You build a tight gather group, then you have to convert that group into a moving convoy without losing the back third on the first ridge. The terrain between the round-up zone and the portal is doing more work than it looks.
On 1,000 or 3,000 sheep modes (Solo Extreme, Solo Insane), Open Country is where the simulation really opens up. The boid flocking behaviour at scale, against real obstacles, with a long drive distance, produces emergent patterns you don't see on smaller maps.
WASD / arrows + Shift to sprint, mouse-wheel or pinch to zoom. On mobile: joystick + sprint. Cycle camera modes with C. The map's scale rewards Free camera (yaw-orbit) when you want to scout the next ridge before committing the flock. The HUD includes a flock counter, gather timer, and portal status.
