General Rules:

The following rules apply to all units, unless stated otherwise in their description:

- All units move and measure distance orthogonally.
- Units may move up to their maximum movement limit and can then attack an adjacent site.

- Attacking a unit will deal damage to it (see damage calculation section).
- If an attacked unit's health reaches zero, it will be removed from the battlefield.
- Defending units that survive an attack, will then deal counter damage to their attacker.

- Units can reinforce an adjacent unit of the same type, instead of attacking.
- Both units must be owned by the same player.
- Reinforcing will convert health from one unit to the other, transferring as much health as possible.
- Any units that are left with zero health after reinforcing are removed.
- A unit which has been reinforced cannot perform any further actions this turn.

The following rules apply to all buildings:

- There are five types of building: Town, Factory, Airport, Dock and Base.

- Attacking a building will deal damage to it (see damage calculation section).
- If an attacked building's health reaches zero, it will gain 50 health and change ownership to the player who attacked it.
- Buildings that are attacked, will not deal counter damage.

- Units can heal at an adjacent building that you own, instead of attacking.
- Healing at a building, will convert health from the building to the unit, transferring as much health as possible.

- Additional units can be purchased using gold at their corresponding production building.
- To purchase a unit, drag it from your hand to an available site next to a production building that you own.
- The cost of purchasing a unit is represented by its count.
- Purchased units cannot move, attack or heal, on the same turn they are purchased.

- Each player receives 10 gold for every Town they own and 20 gold for every Base they own, at the start of their turn.
- Buildings gain 10 health at the end of the owning player's turn, up to a maximum of 100.
- Grey buildings are neutral, and are not owned by any player.

- If a player loses ownership of all their Bases, they lose the game.

Movement Restrictions:

Humans may travel across plains, forests, and shallow water. They may also move 1 space into mountains instead of their regular movement.
Vehicles may travel across plains. They may also move 1 space into forests or shallow water instead of their regular movement.
Aircraft may travel across all spaces.
Boats may travel across shallow and deep water.
Buildings cannot move (obviously).
Units cannot move over enemy or neutral occupied spaces.

//------------------------------------------------------------------------------
Damage Calculation:

An attacking unit deals damage equal to its health, multiplied by its damage factor.
For example, A submarine has a damage factor of 80%, so a submarine with 20 health will deal 16 damage when it attacks (20 x 0.8).
If the defending unit is in shallow or deep water, it takes 25% more damage.
If the defending unit is in a forest, it takes 25% less damage.
Aircraft are unaffected by terrain when calculating damage against them.
All damage values are rounded down to the nearest whole number.

//------------------------------------------------------------------------------

All friendly units and buildings can see tiles up to 2 spaces away.
Aircraft can see tiles up to 3 spaces away.
Boats can see shallow and deep water tiles up to 3 spaces away.
Humans on a mountain can see tiles up to 3 spaces away.
Forest and mountain tiles can only be seen if adjacent to them.
Enemy units and buildings that are not visible cannot be attacked, and have their type and health hidden.
