The player controls clonks, which can perform various tasks ranging from shoveling through dirt and throwing dynamite to mining gold, constructing buildings, and wielding swords. The game world consists of a dynamic and destructible landscape. The landscape is constructed out of different materials like earth, tunnels, sky, coal, ore, gold, and water. Players can destroy solid materials or liquids by using a variety of tools, which allows for dynamic gameplay. Gameplay is focused on two gamemodes:

• Illustration — Artwork of settlement in OpenClonk The gamemode "Settlement" can be played cooperatively, where two or more players work towards a mutual goal. In Settlement, players build settlements using in-game resources such as: wood, metal, fire, and stones. Players face challenges such as inhospitable landscapes, transporting large objects, and natural disasters. The development of Settlements allow players to construct advanced items and vehicles, which allows them to fulfil more complex tasks and achieve various goals. Goals for settlement rounds include: • Wealth: gain a certain amount of gold (called clunkers). • Expansion: expand your settlement to a certain area of the landscape. • Mining: mine a certain amount of valuables like gold or gems. • Statue Construction: gather statue parts and construct a statue.

• Illustration — Artwork of melee in OpenClonk The Melee gamemode is focused on the elimination of other players, which can last between 5 and 30 minutes. The player uses a single clonk to attack enemies with various weapons such as swords, bows, dynamite, grenade launchers, muskets, and catapults. Melee round goals include: • Last Man Standing: players have a limited number of respawns and must survive as long as possible. • Deathmatch: players must achieve a certain number of kills. • Capture the Flag: capture enemy flags and bring them to your base to gain points. • King of the Hill: try to defend a region as long as possible.

OpenClonk development began with the release of the source code of Clonk Rage in February 2009 and a later release under the ISC license in May 2009. The website www.openclonk.org was founded at the same time, acting as a portal for both development and players. The source code and game content were first hosted using a Mercurial repository, but now uses a Git repository. The game engine is programmed in C++ and is cross-platform. The game is available on Windows, Linux and Mac OS X, and can be compiled on FreeBSD. Game content is created using the game's own scripting language C4Script, and is developed simultaneously with the game engine. Since the game content and engine are completely separate, original game content can be created by anyone using the OpenClonk engine. Development of OpenClonk is completely open and contributions from the community are often accepted as patches.
