More of my Free games: Erebus RPG ~ Conquests


Gigalomania is an open source 2D Real Time Strategy god game, available for all popular desktop and mobile platforms, on PCs, tablets and phones. The gameplay consists of researching and developing new technology with which to conquer your enemies, from rocks and sticks to nuclear weapons and spaceships. You can advance through ten different ages, from the stone age to the future. There are 28 different maps to play through.

This game is a work in progress. The gameplay is more or less complete, but the graphics need improving :) Please see below if you want to help out.

Gigalomania is available for: Windows, Mac OS X, Linux, AROS, MorphOS, AmigaOS 4, Nokia Symbian, Maemo, Meego, Android, and Pandora.

Gigalomania should work on any non-ancient Windows, Linux or OS X PC. Gigalomania is tested on Windows 7 and 8 (32 and 64 bit) and Ubuntu 14.04 64 bit, and with Intel Bay Trail, HD 4000 and NVIDIA GTX 675M graphics. Older versions ran okay on Windows XP, and with Intel GMA 3100, NVIDIA (6100, 8600GT) and ATI Radeon HD6570 graphics. Touchscreens/tablets are also supported, this is tested on Windows 8 (tested on the Asus Transformer Book T100). (See the Mac OS X homepage for details on that version.)

For Android, this requires Android 2.3.3, and has been tested on the Samsung Galaxy Nexus and Asus Nexus 7 (2013). A resolution of at least 480x320 is recommended.

For Nokia Symbian smartphones, this requires S60 5th edition (Symbian^1) or later (e.g., Nokia 5800) - the Ovi Store should let you know if it's compatible with your phone. For Maemo, this has been tested on the Nokia N900. For Meego, this has been tested on the Nokia N950.

If the game fails to run, or has problems, please try the following:

On PC platforms, Gigalomania also supports using the graphics from Mega Lo Mania (from the Amiga version - should be in hard disk format, e.g., Whdload version) if you have that game. The "data/" folder should be copied into the main gigalomania/ folder, and then rename the "gfx/" folder to something else (e.g., "xgfx/"). It's up to you to legally obtain the game if you want this feature!


You can also view some videos:


The game can be entirely controlled with the mouse or touchscreen, though additional keys are: P - [un]pause game; Escape - quit and return to start screen. There is also an option to enable a one mouse button interface, rather than requiring two mouse buttons - to enable, go to "Options" (from the screen where you select an Island to play), and click to change to "ONE MOUSE BUTTON UI". This may be preferable for some users (e.g., on touchpads). (Touchscreen-only platforms like Android don't have this option.)

Game types

When you first load the game, you can choose between two game types:

You then choose which colour player you wish to be. Each player has their own special skill:

Main menu

Next you will be shown the main menu. To the top left will be shown an island to play, identified by the text to the left (e.g., "Alpha of the First Age").

There are ten ages in total: 10000BC, 2000BC, 1AD, 900AD, 1400AD, 1850AD, 1914AD, 1944AD, 1980AD, 2100AD. For each island you start in a particular age, and can advance up to three ages in the future (eg, if you start in 10000BC then you can advance until 900AD). Note that different sectors can be in different ages - the age is a measure of the current level of technology, rather than how much time has passed.

The main menu options are as follows:

Main game

See Quickstart, above, for a basic introduction for the game. This section now explains the game and interface in more depth.

The map of the island is shown in the top left. Click on a square to view that sector. You can also move armies by right clicking on a square with one of your armies, and then left clicking on the destination square (not available on touchscreen platforms).

When there are more than two players (including you), you can try forming an alliance by clicking on their player shield (sometimes you may be asked to join an alliance, too). There must always be at least two opposing sides (so an alliance with three players is only possible when there are four sides; if a player is wiped out, this may cause an alliance to break up).

To the left, below the map, is the main control panel which is displayed when viewing one of your sectors. The following icons are available. Many of these icons take you to a sub-menu when you click - to return to the main menu, click the icon that appears at the top of the sub-menu (just below the island map):


Once you have deployed your army (see above), you can move them to another sector by right clicking on the main sector view (not on a building) (for touchscreen platforms, just tap normally) (the mouse icon will change to a shield - for touchscreen platforms, a shield will appear in the top right corner), then click on the square on the map view in the top left, where you want the army to move to. You can also move armies using only the map, by right clicking on a square to select an army in that square (non-touchscreen platforms only).

To return an army to a tower in one of your sectors, first move the army to that sector (if not there already). Then select the army by right clicking on the main sector view (or normal tap for touchscreen platforms), then left click on your tower (the main building with four turrets).

In later ages, you will find maps that have squares not connected (i.e., separated by sea) - in these cases, only air units can move between them. Air units are available in ages 1914AD, 1944AD and 2100AD.

The offensive weapon corresponding to 1980AD is a nuclear missile, which can be used to destroy any sector completely! This is deployed like a normal army, but such an army can only contain 1 nuclear missile, and nothing else.

The defensive weapon corresponding to 1980AD is a nuclear defence. This does not defend your sector, but if the sector is nuked, one of these will launch and nuke the sector from where the nuclear missile came from.

The defensive weapon corresponding to 2100AD is a laser. This defends both against conventional and nuclear attack.

As well as attacking your enemies, an army can build new towers in unclaimed sectors. When your army is in a sector with no other players, a clock will appear as they build a new tower. Once the tower is built, you have control of the sector just like your first sector. Note that sectors you control behave fairly independently - e.g., each sector has its own set of designs, elements and so on. Only people and offensive weapons can be transferred between sectors, by deploying armies.

Suspended animation

When a sector reaches 2100AD (possible in Age 7 onwards), it is possible to place some of your people in suspended animation, to "save" them. This has no real effect when playing in "Single Island" mode, but in "All Islands" mode, it contributes to your final score if you complete the game (finish all the islands).

Choosing windowed or fullscreen mode

Gigalomania runs in fullscreen mode by default on most platforms, but you can in windowed mode by running from the command line with the argument "windowed". E.g., on Windows, run with:

gigalomania.exe windowed

On Windows you can also doubleclick on gigalomania_windowed.bat to run in windowed mode.

On platforms where Gigalomania runs in windowed mode by default, use the command line option "fullscreen" to force fullscreen mode.
