Can you walk a four-legged robot across ice, quicksand, rivers and lava – without dropping a single crate?
In Quad Walker you control every leg yourself. Drag a foot, place it on the ground and watch the knees bend in real time thanks to inverse kinematics. Lift a leg and that side sags. Lean too far and the cargo starts to slide. Every step is a small balancing puzzle.
🦿 REAL STEP-BY-STEP CONTROL
• Move each of the 4 feet with your finger
• Raise or lower the front and rear of the platform
• Shift the body forward or back to keep the centre of mass over your feet
• Watch the spirit level – tilt too much and the cargo goes over the edge
🌍 16 HANDCRAFTED LEVELS, 9 WORLDS
Test centre, green hills, Mount Olympus, desert dunes, red canyons, frozen peaks, volcanoes, the Moon and a raging storm. Each world brings something new:
• Ice that makes your feet slide
• Quicksand that swallows your legs – pull them out!
• Rivers – keep the cargo dry
• Lava – one wrong step and you burn
• Low gravity on the Moon
• Wind gusts, earthquakes, deep potholes and boulders
Later levels get longer and harder.

⚙️ DIFFICULTY & PHYSICS
Four difficulty levels from Easy to Nightmare, with an energy system on Normal and above. Choose Normal physics, or Extreme physics with inertia, toppling cargo, gusts, quakes – and a robot that can tip over.
🔧 3 ROBOTS, 11 UPGRADES
• QUAD-WALKER – the balanced classic
• MANTIS – inward knees, steadier and more efficient
• STRIDER – 3-joint legs, tall with huge reach
Each robot has its own upgrades: grip deck, side rails, gyroscope, shock absorbers, bungee straps, wider platform, longer legs, non-slip feet, lava shielding, a picker arm that recovers fallen crates, and a bigger battery. Five normal levels plus three ULTRA levels per upgrade.
