Coldwater County: Offroad 4x4

Build a 4x4, then find out what it can climb.

Coldwater County is an offroad truck simulator for people who care how a truck really works. Lock the diffs, drop into low range, air down to 15 psi and pick your line up slickrock, through bayou water and over snowbound ridges.

THE TRUCKS • Six rigs: a midsize pickup, a V6 SUV, a short-wheelbase two-door 4x4, a 6x6 fire-and-rescue wrecker with a winch, a 1,025 hp quad-motor electric SUV, and one secret rig for drivers who take Gold on every trail. • Fit front and rear lockers, a 2, 4 or 6 inch lift, 35 or 37 inch mud-terrain tires, a turbo or twin turbo, rock sliders, a skid plate, a winch bumper, an LED light bar and an extended fuel cell. • 19 paint options, including iridescent color-shift finishes, plus rim colors. • The build sheet shows what every part changes: diff and frame clearance, crawl ratio, tip angle, approach, departure and breakover angles, weight split. Bigger tires raise the diff. A lift kit doesn't.

THE DRIVING • 2H, 4H and 4L low range, front and rear diff locks, sway bar disconnect, traction control and tire pressure, all switched out on the trail. • A winch for when the line runs out. • Grip changes under every tire: asphalt, gravel, dirt, grass, rock, sand, mud, snow and ice. Rain soaks dirt into mud. • Weather and a day-night cycle: fog, rain, snow, dust, thunderstorms with lightning, and night runs on headlights. • Engine sound built from real recordings, matched to RPM.

THE PLACES • Coldwater County: an open-world hub with a Main Street town, highway traffic and signed roads out to the trailheads. • 10 timed off-road trails: Kestrel Pass, Vermillion Mesa, Ochre Narrows, Sable Dunes, Coyote Wash, Whiteout Ridge, Saddleback Highline, Mosswater Bayou, Ember Canopy and Hoodoo Rim. Alpine switchbacks, red-rock mesas, sand dunes, a dry wash, snow timber, swamp crossings, a smoking volcanic rainforest and a hoodoo canyon rim. • 5 expert rock crawling parks: Cathedral of Stone, The Enchantments, Slickrock Sand Park, Katla Caldera Rift with its ice cave, and the Moon at half gravity. • Deer, elk, jackrabbits and ravens share the trails.

THE CAREER • Start with a pickup and $750. Earn permit stamps from Open up to Class 1 to unlock harder country. • Chase Gold, Silver and Bronze medals, and run-card challenges: stay in 2WD, leave after dark, finish with a quarter tank, never use Recover. • Take Dispatch recovery jobs in the 6x6 tow truck: free stuck and tipped trucks at 38 sites across the county and its trails. • Manage fuel or charge, wear and repairs. A wreck costs you a tow. • 30 achievements.
