Four-player touch. Each quadrant belongs to its numbered pilot. Left stick steers, the throttle stays where you leave it, and Fire/Drop acts only for your vehicle. Pause stops the entire world. In face-to-face seating the far pair rotates 180°. One person at a time drives a vehicle; choose an unoccupied unit from the map.

Steady flight. The stick commands a bank and climb angle. Releasing it returns toward level flight. This is an optional arcade control aid, not a full aerodynamic model. Low airspeed still causes stalls. Manual controls retain roll and pitch input.

Combat guidance. The aiming reticle shows barrel direction. It does not predict a future landing point. Combat rounds include random spread. This combat workshop is not yet an assessed calibration lab.

Planes. Along the flight path, m·a = T − k·v² − m·g·sin θ, where θ is the climb angle. Top speed comes when thrust equals drag, so v = √(T/k). Climbing trades speed for height. Banked turns follow v²/r = g·tan φ, and pulling up is limited to 6 g, so the turn rate is at most 6g/v. A slower plane turns tighter. Game rules: the wings keep your velocity pointed where the nose points, and below stall speed the nose drops.

Gyro-copter. The rotor pushes along its own axis. Net force = thrust + weight + drag. It hovers when thrust equals weight, which is the white mark on the throttle. Tilting sends part of the thrust sideways, so you move but need more throttle to stay up. Game rules: the chin gun tilts up and down toward targets by itself, and drag is −k·|v|·v.

Ships. Along the heading, m·a = T − k·v², so top speed is √(T/k). The rudder turns the ship at a rate of v/R, so a ship barely turns when it is stopped. Ships need water at least 3 m deep and stop when they run aground.

Cannon shells. Each shell leaves at the gun’s muzzle speed v₀ at the elevation you set, plus the ship’s own velocity. Only gravity acts after that. For a stationary launcher and equal launch and landing heights, R = v₀² sin 2θ / g, so 45° reaches farthest. A raised muzzle or moving vehicle changes that result. Hide the splash marker and pilots must work out the elevation from the target distance themselves.

Zeppelin. Net vertical force = buoyant force − weight. Up and down change the buoyant force by up to 8% (game rule: venting gas or dropping ballast). Bombs inherit the airship’s full velocity. For level flight, initial vᵧ = 0 and t = √(2h/g), where h is the release height above the landing surface. This practice does not certify written work.

Cars. Chassis retain their mass, drive, drag and grip. Responsive steering and drift are disclosed game assists. Four wheel contacts support slopes; departures and boost jumps use gravity 9.8 m/s² and swept landing contacts. Two finite boost charges recharge in simulation time. Bumpers transfer momentum according to chassis mass and closing speed with a 0.62 restitution coefficient. Contact damage is deliberately gentle; damage and recovery are simplified game rules. The expanded two-island track has six sectors and ordered gates. Model appearances keep the selected chassis physics and hitbox.

Motorcycle. Light and quick, so its drive is limited by grip, not the engine: a bike accelerates at most μ·g. In a corner it leans so that tan φ = v²/(g·r), the same rule a banking plane follows. The screen shows the lean angle.

Hovercraft. It floats on a cushion of air, so there is almost no friction. Turning the hull does not turn your velocity: momentum keeps you sliding the old way until thrust changes it (Newton’s first and second laws). To corner, point the thrust along the change in velocity you want. It crosses land and water, but gravity pulls it down slopes and it cannot climb hills steeper than its thrust allows. Drift shows the angle between where you point and where you go.

Tanks. The same force balance as a car, with different mass and drive force. Tracks can turn the hull while standing still. Tanks use the land routes and cannot cross deep water. The mortar fires only between 45° and 80°, so it uses the high-angle solution: with a stationary launcher and equal launch and landing heights, complementary angles have equal range (except the single 45° maximum).

Flagship battle. Each commander picks a sea, land or flying flagship, including the approved Sol Heirs and Gaian Enclave hulls. SH uses a fixed forward railgun with a ten-second charge and hull recoil. GE uses an articulated ventral energy cannon. Both ships have working secondary weapons and swappable Simple / Two-thumb assisted helms. Stop Turn, Stop Ship and Level are separate commands; assisted altitude is world-vertical, with body-axis trim available separately. Switch local stations for mounted weapon optics, or use Outside view for orientation. Unoccupied AA tracks enemy aircraft within its firing limits and yields when a player takes the station. Optional sight practice remembers learned relationships while updating the current trajectory as you aim or move. This prototype does not provide full cockpit interiors or a shared-hull network crew; flight and weapon balance remain provisional. Units deploy from the marked grid, harbor, airfield or depot. Any team vehicle can clear the next numbered gate: +3 team gold and a new racecar spawn. Hold capture points for +1 gold every 5 simulation seconds each. A human-fired finishing hit on an AI vehicle earns +1 gold; destroying a human-controlled vehicle earns +2 gold. Dredges collect gold for upgrades. Vehicles are free within the team limit and respawn 10 seconds after destruction. Swap vehicles in the command map’s Vehicles menu. Gold buys upgrades only. Small guns do only a fifth of their damage to flagship armour. The objective is to destroy the opposing flagship.

Gun rounds. Plane and gyro-copter rounds leave at 300 m/s relative to the craft, plus the craft’s own velocity. Only gravity acts after that. Not modeled: wind, waves, fuel, real wing shapes.

Scoring. Downing or sinking an enemy scores a point for your team. Crashing into the ground or sea gives the other team a point.
