Chaos Esque Anthology is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.

Chaos Esque Anthology is a first-person shooter forked of Xonotic, it includes new features such as extended number of weapons (including medieval weapons), new maps, vehicles, spellcasting, monsters, player characters, textures and game modes.

Chaos Esque Anthology has been in continuous separate development from Xonotic since forking from it in 2012. An example of such development is to compare the amount of weapons from before the fork in 2012 to the current number in the Chaos Esque Anthology project. The pre-fork amount was approximately 18 weapons. The current number of weapons in Chaos Esque Anthology is over 200 weapons. Approximately a ten-fold increase. This gives a glimpse into the amount of work that has been invested into the game.

The spellcasting system has been expanded from non-existence to fifty (50) spells. Alongside medieval weapons and the quest-spawns option, this system allows a player or server admin to set up a game that is similar to rouge-like classics, in 3d, if he wishes. Other options include modern weapons and futuristic weapons.

The amount of vehicles in the game has been expanded from five to over thirty. Additionally there is a buildable building system and a city generation system. Monsters are also supported and can be placed by the map author or spawned into a map via mutator. Furnishings can be built via the buildable-building system and/or placed by the map author. City-generation buildings can also be placed by the map author in addition to via the city-generation mutator. More in-depth information as to how to use these systems is included in the game on the Info page.

The game now features a more-advanced damage calculation method for melee weapons; allowing for multiple regions of the target which modify the damage taken based on the type of weapon used.

Childish Cannoneer is the first venture of the "Indie Games" project hosted by White Island Software at the Gambas Forum, and participated in by Piga Software through Graham L. Wilson. The aim of the project is to make computer games to show off the Gambas language, with the eventual hope of inclusion in the Humble Indie Bundle for maximum attention. It is to feature a little boy building a makeshift air cannon from spare parts only to terrorize his older sister, and potentially the whole neighbourhood, while evading the wrath of his father. The majority of the game's multimedia are derived from vector graphics taken from OpenClipart and sound effects taken from SoundBible. Contributions to this project, or the creation of other entities for the Indie Games project, are more then welcome.

Colobot is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.

Colobot - colonise with bots - is a combination of a real-time strategy and a programming game. The player takes the role of an astronaut with the mission to find a habitable planet, after humankind plunged the Earth into an ecological catastrophe. The player is not on their own, but accompanied by programmable robots that can help in building and defending structures. Through a satellite link with 'Houston' she/he is directed to complete a number of missions on different planets. The game also involves a rather aggressive though evolving relationship with native alien lifeforms.

Apart from the missions, there are also two game modes that instruct the player in the use of CBOT, the language used to program the bots. This language is rather similar to C++ and Java. During the missions, it's not really necessary to write code for the bots, but it is convenient to be able to adapt the programs Houston offers to the player. Version 0.1.6 introduced the Code Battle game mode, where players first provide all programs needed to operate a base and/or kill all enemies, and then let the programmed bots do their job without the possibility to interfere. The game provides three types of enemies: passive targets, pre-programmed bots and hot-seat play against a fellow human.

Limbs Off is a free game. This means that the source code is available to be studied, modified, and distributed. Most projects look for help with testing, documentation, graphics, etc., as well.

Limbs Off is the flagship in plaimi's phun-fysics genre, in which they strive to reproduce complex real life physics, but take certain liberties whenever they feel it will add to the entertainment of the games. Limbs Off specifically is a fighting game that takes place in space. Right now there is only one planet and three characters, but plaimi want to implement several planets as well as inter-planetary travel via cannons, amongst other features[240].

The characters are "limbless", and consist of a head, body, two feets and hands. As of yet, the only way of "fighting" is running into each other. When the characters hit each other, their mass is decreased up to a point where their body parts are unlinked and the characters effectively become space junk[241].

The source code is licensed under the GNU GPL[242], and plaimi encourage people to contribute with code, make their own art, and make packages for UNIX package managers[243].

Limbs Off does not come with sprites or sounds. Instead, plaimi want to hack the game to load art from a data directory, so that users can install their own art. As of yet it only supports this with character sprites[244], as the game is at a very early alpha stage. It "went public" on the 24th of September in 2011, on github[245].

The game runs on relatively modest hardware, and has been compiled and run successfully on most modern UNIX-based operating systems[246].
