|Chaos Esque Anthology||2020-02-15||1st person shooter|
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.
Freedoom is a project aimed to create a complete and free Doom IWAD file, which contains all game media. Combined with the GPLed Doom Source (such as PrBoom or GZDoom), this makes a completely Free (as in speech) game. Freedoom's data is licensed under the Modified BSD License.

The gameplay is very fast-paced, and includes and encourages a form of bunny hopping as well as rocket jumping (in Xonotic "laser jumping" is more common). The art is mostly futuristic, but unofficial maps exist in a variety of styles.
There are 16 different game modes (including the classics: deathmatch, team deathmatch and capture the flag, but including uncommon ones such as a type of football), 16 weapons with secondary fires, 18 official maps (and a lot of unofficial maps), and a complex HUD editor that lets you tailor the HUD to your exact preference. There are also so called mutators, that allow to slightly modify rules of each game mode.
