    Curse of War -- Real Time Strategy Game for Linux.
    Copyright (C) 2013 Alexey Nikolaev.


This is a fast-paced action strategy game for Linux implemented using ncurses user interface.

Unlike most RTS, you are not controlling units, but focus on high-level strategic planning: Building infrastructure, securing resources, and moving your armies.

The core game mechanics turns out to be quite close to WWI-WWII type of warfare, however, there is no explicit reference to any historical period.

See "How to play" section for more details.

Build, Install, Uninstall

  1. Build with make (Linux)

    Ncurses version: $ make

    SDL version: $ make SDL=yes

    To install, "make install" with defined variable DESTDIR. See file INSTALL for details.

  2. Build with CMake (Linux or Windows)

    See COMPILE-WITH-CMAKE for details.

Command line arguments

-W width Map width (default is 21)

-H height Map height (default is 21)

-S [rhombus|rect|hex] Map shape (rectangle is default). Max number of countries N=4 for rhombus and rectangle, and N=6 for the hexagon.

-l [2|3| ... N] Sets L, the number of countries (default is N).

-i [0|1|2|3|4] Inequality between the countries (0 is the lowest, 4 in the highest).

-q [1|2| ... L] Choose player's location by its quality: 1 = the best available on the map, and L = the worst. Only in the singleplayer mode.

-r Absolutely random initial conditions, overrides options -l, -i, and -q.

-d [ee|e|n|h|hh] Difficulty level (AI) from the easiest to the hardest (default is normal).

-s [p|sss|ss|s|n|f|ff|fff] Game speed from the slowest to the fastest (default is normal).

-R seed Specify a random seed (unsigned integer) for map generation.

-T Show the timeline.

-E [1|2| ... L] Start a server for not more than L clients.

-e port Server's port (19140 is default).

-C IP Start a client and connect to the provided server's IP-address.

-c port Clients's port (19150 is default).

-v Display the version number

-h Display help information

How to play

A good and easy mode to start playing: $ curseofwar -i4 -q1 -dee

Or, on a smaller map: $ curseofwar -i4 -q1 -dee -W16 -H16

Normally, the game starts with 4 small countries in the corners of the map. You start as the ruler of the Green country, and your goal is to conquer the whole map.


The map is made of hexagonal tiles. They are:

/^ Mountains, cannot be populated

/$\ Gold mines, cannot be populated too. This is the source of gold for your country. To control a mine, surround it with your army

n Villages, have the slowest population growth (+10%)

i=i Towns, average population growth (+20%)

W#W Fortresses, high population growth (+30%)

  • Grassland, normal habitable territory


People are your primary resource. Thriving population is essential for your victory.

Every tile can support at most 499 people from each country. When people from more than one country occupy the same tile, they fight. The country that has the highest population at the tile is called the tile owner.

The population of the tile owner is shown on all grassland tiles as follows:

. 1 - 3 citizens .. 4 - 6 ... 7 - 12 : 13 - 25 .: 26 - 50 .:. 51 - 100 :: 101 - 200 .:: 201 - 400 ::: 400 - 499

People migrate from highly populated tiles to less populated tiles.

Population grows only in cities. In villages by 10%, in towns by 20%, and fortresses by 30% every simulation step. By controlling cities, you control their surrounding territory.


Every country can put flags on the map. Flags change migration rates, so that people of your country start gathering at the tiles with flags.

Player's flags are shown as white "P" on the right side of a tile. Flags of the computer opponents are shown as "x" on the left side of a tile.

The flags can be used to increase population of your own cities, as well as for conquering foreign territories.

When countries are fighting for a city, and if the damage to the defender's army is significant, the city can be destroyed: A fortress becomes a town, a town becomes a village, and the village gets completely burnt by the invaders.


Computer opponents differ in personality, and it affects the way they fight.


Arrow keys and H, J, K, L are for moving the cursor

R or V build village -> town -> fortress

Space add/remove a flag X remove all your flags C remove a half of your flags

S slower F faster

Q quit


To start a server for two players: $ ./curseofwar -E 2

To start a client and connect to the server: $ ./curseofwar -C

To specify ports, use -e option for server's port, and -c option for client's port. By default, servers are using port 19140, and clients are using port 19150.

  Start a server for a single client using port 11111
    $ ./curseofwar -E 1 -e 11111

To connect to it: $ ./curseofwar -C -e 11111

Alternatively, to connect to it using port 12345 on the client's side: $ ./curseofwar -C -c 12345 -e 11111

Note that all needed map options must be setup when you start a server, the map and other data are transmitted to clients, once they are connected.

  Server for 3 clients, no computer opponents, hexagonal map, and equal 
  conditions for all:
    $ ./curseofwar -E3 -l3 -S hex -i0 

Game speed cannot be changed by a client, so it must be set initially by the server. Not all data is sent to clients (e.g. info about population is not sent in full).

Multiplayer mode is at relatively early development stage. Changes may occur at any moment. When you play with other people, make sure that you are using the same version of the game. Hopefully, game's client-server communication protocol will be improved in future. All communication is made via UDP.

Please, report you problems with multiplayer.
