The aim in each irrlamb level is to touch every glowing globe, sometimes within a time limit. In some levels the player has the grapple upgrade, which allows the player to shoot an elastic rope at objects and terrain and can be used to climb walls.

OpenArena’s gameplay is the exact same as Quake III Arena - score frags to win the game using a balanced set of weapons each designed for different situations. Gameplay modes exist such as deathmatch, Team Deathmatch, Tournament, and Capture The Flag (all modes also in the original game). Bot support was added in version 0.6.0.

OpenArena has undergone compatibility testing with some Quake 3 mods.Open Arena does not have a set story line. The models do not follow a set theme with some being military, fantasy, or oriental themed.

In a game of BZFlag, players drive around tanks, viewed from a first-person view, in a server-defined world (also known as a “map”), which can be modified. Tanks have the ability to drive through other tanks, but cannot travel through buildings or other world objects. The basic objective is to destroy opponents’ tanks, which are tanks of another team’s color. For example, green tanks are supposed to try to destroy red, purple, blue, and rogue tanks. Rogue tanks do not have any allegiances to a certain team and are therefore able to kill anybody.

Each player controls the team of his choice (penguin, gnu, firefox, wilber,…) and must destroy his adversary using more or less casual weapons.

Although a minimum of strategy is required to vanquish, Wormux is pre-eminently a “convivial mass murder” game where, turn by turn, each member of each team attempts to produce a maximum of damage to his opponents.

Some of its features include:

* 3D Engine based on Qfusion (a modification of Quake 2 GPL engine)

* eSport oriented FPS

* Fast-paced gameplay focused on trix (trick jumps) and art of move

* Complete Power-up System including Weak and Strong fire mode for each weapon

* Cartoonish graphics with celshading-like_but_not_Manga style, mixing dark, flashy and dirty textures, matching with action full of fun and speed

* References : Quakeworld, Quake3 CPMA, Jet Set Radio, Speedball.

It uses the platform independent library SDL and, since version 0.98, the OpenGL accelerated Graphics Renderer. The game is developed in C++.

Players take the role of a tribe leader in 4000 BC and have to guide their people through the centuries. Over time, new technologies are discovered, which allow the construction of new city buildings and the deployment of new units. Players can wage war on one another or form diplomatic relationships.

The game ends when one civilization has eradicated all others, accomplished the goal of space colonization, or at a certain deadline. If more than one civilization remains at the deadline, the player with the highest score wins. Points are awarded for the size of a civilization, its wealth, and cultural and scientific advances.

At its lowest level, Scorched 3D is just an artillery game with two+ tanks taking turns to destroy opponents in an arena. Choose the angle, direction and power of each shot, launch your weapon, and try to blow up other tanks.

But Scorched 3D can be a lot more complex than that, if you want it to be. You can earn money from successful battles and use it to invest in additional weapons and accessories.

You can play with up to twenty four other players at a time, mixing computer players with humans. There’s a variety of changing environmental conditions and terrains to be dealt with.

There are 46 standard maps to choose from, 5 player characters, and 9 weapons with alternate fires, and a grappling hook. The game is powered by the id Tech 2 based CRX Engine, which features 32 bit hi-res texture support, shaders, textured particles, stain maps, reflective water with refractive shaders, light bloom, real-time shadows, real-time vertex lighting, normal-mapping, and other modern effects, all of which can be turned on or off in the menu.

Also featured is an internal server browser for finding other people to play online and the external Code Red Galaxy program which also serves as an IRC interface.
