Empire

A turn-based military strategic game.

Introduction

Do you have it all to conquer the world?

Veni, vidi, vici. (I came, I saw, I conquered.)—(JULIUS CAESAR)

This is a round-based military strategic game, in other words, a war game. You start on a map, owning one city. From there, you can produce military units that can explore and conquer the world. But you are not the only one on this map, so soon the fighting will start.

You win the game when you are the only player left on this map. A player can be defeated the hard way: The player loses all cities and all units. Or the player decides to resign.

War does not determine who is right—only who is left.—(ANONYMOUS)

Start a new game

When you start a new game, you have several options to adapt the game to your needs.

Game rules complexity

To offer something both for novice and expert players, there are different types of game rule sets.The rules are the same for all players of the game.

  Beginner

This game is for getting used to the game concepts. The following rules apply to this type of game:

• The world is openly visible to all players. So there is no need to explore the world.
• Only border, sea, land and city fields. Terrain types of the different land fields have no effect.
• Only army, transporter, destroyer, cruiser and battleship units.

  Standard

This game is for players with fun in exploring. The following rules apply to this type of game:

• Fog of war is active, so each player only sees those parts of the map the player has already explored. Even that knowledge of fields, once explored, decays: Imagine you once saw an enemy unit there; you have to move a unit near to that field to see if the enemy is still there. (Outdated fields are drawn a bit grayed-out.)
• Only border, sea, land and city fields. Terrain types of the different land fields have no effect.
• Only army, fighter, transporter, destroyer, submarine, cruiser, battleship and carrier units.
• Cities that continue to produce the same type of unit consecutively get a bonus of ¹/₆ on their production for all but the first unit.

  Advanced

This game is for advanced players. Compared to the standard game, the following rules apply to this type of game:

• New terrain types for land fields add more strategic complexity: Rough, river, forest, and mountain.
• All unit types available.
• For most units, enemy air units can be seen in distance of 2 fields.
• Damaged units have their attack strength reduced by 50%.
• Production in cities gets more complex:
  • Cities start with a random productivity between 60% and 160%.
  • Some cities are specialized on units types. If so, this unit type is listed in blue and marked with an asterisk in the production dialog. For this unit type, the city is 20% more productive, unfortunately it is 10% less productive for all other unit types.
  • Air units can bombard cities. If they win, either the unit in production will be destroyed, or the productivity of the city is decreased by 10%.
  • Cities have to support existing units. If your number of units is more than double your number of cities, then productivity of all cities is decreased further for each new unit. (A city producing nothing counts double here.)

World size horizontally

The width of the world.

World size vertically

The height of the world.

Topology

Chooses the number of neighbors a field has

  Squares, 8 neighbors (original Empire)

Units can move also diagonally.

  Squares, 4 neighbors

Units can not move diagonally.

  Hexagons

Just like honeycombs, each field has 6 neighbors.

  Hexagons hor.

Just like honeycombs, each field has 6 neighbors. Horizontally aligned.

World borders

Chooses if the world has borders or bends in itself.

  Rectangle (surrounding borders)

  Globe (north/south borders)

  Torus (no borders)

City density

A higher value will create more cities, a lower value less.

Land density

A higher value will create more land, a lower value more sea.

Continents size

A higher value will make larger land masses, a lower value more small islands.

Quickstart

If selected, all players start the game with some pre-produced military units.

Name

The name of the game, for naming saved games. (Optional.)

View

Settings how the game looks like or behaves for the current player, or informative dialogs for the current player.

  Center screen

Centers the screen onto the current unit.

  Zoom level

Zooms in or out on the current player's map.

  Zoom level 1 (64x64, extremly detailed)

  Zoom level 2 (32x32, very detailed)

  Zoom level 3 (24x24, detailed)

  Zoom level 6 (4x4, overview)

  Zoom level 7 (2x2, high-level overview)

  Perspective

Shows the world from other player's or all-knowing perspective. Only available in standard ruleset or advanced ruleset, and when either you or all other players have been defeated.

Only when showing the player's own perspective, the player can change views or give units orders or commands.

  World

Shows the world as it is.

  Normal view

Shows both units and cities, and leads through your units.

  Survey view

Shows both units and cities, and lets you freely explore the map. When you set focus on a unit or city you own, returns to normal view, so you can give it new orders.

  Production view

Shows only cities with their production on the map.

With sufficient zoom, for each city is additionally shown:

• below the city an orange bar shows production progress,
• in the advanced ruleset, above the city a white bar shows the city productivity. (If that bar is also drawn in orange, then the city is currently not producing the unit type the city is specialized in.)

  Path view

View for editing automated move paths.

Move paths are useful to give the same orders to all future units, e.g., to bring freshly produced units from the rear to the front line. Each fitting unit that begins a turn on the starting field of a path, is not damaged and has no other commands to follow gets the according go to command.

Move paths can be defined separately for land, sea and air units. They must all start on the player's city (or airbase in case of air units). The end position must be reachable for the unit type, not lead to a circular path route for any military branch, and in case of air units the end position must also be a city or airbase in reach.

To create or edit a path, you have to click on the start point of the path. This opens a dialog where you can edit all paths starting from that position. When you press the button "Create new path", the dialog will disappear, until you click the end point of the new path.

You can't remove a path by yourself. But you can make it applicable for none of the military branches, then the system will remove it when you leave the dialog.

Orders

Orders for the current unit of the current player.

Production...

Changes production.

Only applicable for cities.

Move paths...

Changes move paths starting this position.

Only applicable in path view, and only for cities and airbases.

  Go to

Gives the unit the order to move to a destination.

The computer only offers destinations this unit can reach on its own. When choosing the path, the computer takes the terrain into account, but no other units in the way.

Before moving onto a field owned by enemies, you have to repeat the command from the neighboring field. (This helps preventing accidental attacks.)

  Escort

Gives the unit the order to escort another sea unit.

Only applicable to sea units. The user selects the target sea unit to escort. From then on this sea unit will try to follow the target sea unit at the best of its abilities.

Go home

Gives the unit the order to return to next own city (or airbase or carrier for air units). If multiple cities are equidistant, one will be chosen at random.

Useful for units with limited range (like air units), or for damaged units for repair.

Explore

Gives the unit the order to explore areas not explored so far.

Unit will head to the nearest unexplored area and start to explore it. It will try to maximize the amount of terrain it can explore, but will prefer short-term gains to long-term gains. The unit will clear this order on its own initiative, if

• it's getting low on fuel (for units with limited range),
• it passes a neutral city (for land units),
• or there is no unexplored terrain within reach (or a reasonable number of turns away).

Sentry

Gives the unit the order to sentry and wait for new orders.

Useful for guarding units, or for land units waiting for their transporter, or for loaded units.

Not applicable in cities. For air units only applicable in safe places like carriers or airbases.

Load units

Gives the unit the order to load other units.

Applicable for transporters and carriers, when outside of a city.

The unit remains at position until fully loaded. Each fitting neighboring movable unit that is sentry or without orders is loaded.

Unload units

For transporters and carriers: Wakes up all contained units for unloading.

Build airbase...

In the advanced game, for armies and tanks: Builds an airbase. The building unit is used as garrison and will therefore disappear.

Clear orders

Clears the unit's orders.

Clear alerts

Unit can continue its path.

Disband unit...

Disbands unit.

Rename...

Renames unit or city.

  Next

Changes focus to next unit.

This is not an order but a command, so any other order the unit may have is not affected.

Useful to let other units move first this turn, e.g., because they are in the way, or they shall attack first.

Skip turn

Unit won't move this turn.

This is not an order but a command, so any other order the unit may have is not affected.

A city might repair a damaged unit that skips turn and stays in the city.

Also useful, if you're not sure what to do with this unit, but don't want to sentry, e.g., because you want to be reminded every turn, or it's in a city, or because a passage is currently blocked by another unit that will move away next turn.

A unit you skipped the turn for won't be focused again in normal view this turn, but in survey view you can still pick the unit and thereby revoke this command.

  End turn

Ends turn for current player, so the next player can move.

To end the turn, you must be in normal view, and all your units must have moved or skipped their turn.

During the game

You can use the following input methods (besides the menu options) during the game.

Keyboard Actions

Mouse

A left mouse click on any position could (if unambiguous and non-critical) lead to a direct action, or information in the status bar, or shows a context menu of the options with this position. The possible options depend on

• the active view mode,
• if the field contains units that could gain focus,
• if currently a unit is in focus that could reach or attack this position.

Fields

A map is not the territory—(ALFRED KORZYBSKI)

  Unexplored

In standard and advanced games, when the game starts, nearly all terrain is shown as unexplored. The real terrain can be uncovered by moving one of your units onto or near to it.

The whole art of war consists in getting at what is on the other side of the hill, or, in other words, in learning what we do not know from what we do.—(DUKE OF WELLINGTON)

  Border

A field that no unit can move to, cross, attack, or do anything else with it. Marks the edge of the map. As nothing can happen on this field, it never outdates.

  Sea

A field that only sea units or air units can move to. Can take only one unit at a time.

  Land

A field that only land units or air units can move to. Can take only one unit at a time.

  City

It is vital for success to conquer cities, as cities can produce military units.

A city is a field that can be conquered by land units. If successful, the city gets colored by the player's color, and the player can choose what unit this city will produce. The conquering land unit is used as garrison for the city and will therefore disappear.

Any city owned by a player can produce land units and air units. But only cities neighboring a sea field can produce sea units. A neutral city produces nothing.

A neutral city or enemy city can be conquered by land units. Air units can attack the city's production or enemy units residing in the city. Sea units can do nothing with them.

In your own cities, you can stack as many units as you want to. Even more, air units can land in them, and damaged units can be repaired by staying in them.

In combat, cities can not attack, only defend themselves. They do this with a defense rating of 2 and a damage rating of 1.

  Rough

A land field. Additionally, in the advanced game,

• tanks are slowed down to 1 move per turn when entering this field.

  River

A land field. Additionally, in the advanced game,

• tanks are slowed down to 1 move per turn when entering this field,
• and all land units get their defense rating doubled against tanks.

  Forest

A land field. Additionally, in the advanced game,

• tanks are slowed down to 1 move per turn when entering this field,
• and all land units get their defense rating doubled against all attackers except army.

  Mountain

A land field. Additionally, in the advanced game,

• tanks cannot enter this field, but still can attack units in it,
• and all land units get their defense rating doubled against all attackers except army.

Units

Military units are essential for your success. As each kind of unit has its strengths and weaknesses, you need to understand how to use them most efficiently.

Not all units are available in all game rules complexities, and sometimes there are subtle differences of the units' properties between those, so all unit properties are listed for all complexities. Properties are:

Type

Either land, sea or air unit.

Turns to produce

How many turns it takes for a standard city to produce the first unit of that kind.

Sighting range

How far this kind of unit can see and explore new territories. Also applies for enemy sighting alerts.

Load

The kind of load this kind of unit can take, if not damaged or hindered otherwise. Names the number of cargo holds this kind of unit provides, the kinds of units it can load, and for each of those the number of holds that kind of unit takes.

Moves per turn

How many moves this kind of unit can move per turn, if not damaged or hindered otherwise.

Moving range

Air units need to refuel within their unit range, or they crash and get destroyed. They can refuel by landing in cities, on carriers or on airbases.

Move-over

Air units can move over other units—but they must end their turn on a field on their own, or on a field they can land on. While a unit is moving over another unit, no other unit might move, so actions like Next and Skip turn cannot be performed then.

Maximum damage

The number of hits this kind of unit can take before it is destroyed.

Can attack coastal units

Only applies to sea units. Indicates if this kind of unit can attack land units standing on the shore.

Attack strength

Defines how likely this unit will win a combat round when attacking.

Defense strength

Defines how likely this unit will win a combat round when attacked.

Shot damage

If this unit has won a combat round, defines how many hits the enemy gets.

  Airbase

This is a strange kind of unit: Airbases are not produced by cities. An army or tank on a land field can "build" and transform permanently into an airbase. An airbase, once installed, cannot move. It can only be disbanded. If successfully attacked, it will be destroyed, and all contained units will be lost.

It can hold up to 8 fighters or bombers, but no other units. Especially, the field is forbidden to be entered by land units, even if the airbase is built on land.
