Vendetta Online

The twitch gameplay in Vendetta Online revolves around lining up a correct shot against enemy ships, while avoiding incoming fire. The dynamics of this can be complex, as ships are moving through 3D space, and the weapons fire itself has a specific velocity, modified by the ships' absolute velocity. The ships mostly obey the laws of Newtonian mechanics although a few artificial limits are put in place to increase the playability of the game. The control scheme includes a full six degrees of freedom, allowing users to assign keys or control axes (via joystick, thumb-stick, throttle, accelerometer, or touch area) to yaw, pitch, roll, and thrust along three axes.

Ships can also be controlled with the mouse and keyboard using "mouselook" mode, in which the direction of view is controlled by the mouse and the ship's nose auto-corrects to catch up. Ships each have detailed specifications such as mass, thrust, torque, cargo capacity, top speed, turbo energy drain, armor, and weapon ports. There are also many variants of the main ship types, some holding certain advantages over others, with some advanced variants belonging to special factions. Depending on what equipment is being used, and what is carried in the cargo hold, the mass of the ship (and consequently maneuverability) will change greatly, affecting combat.

Vendetta Online has a long backstory, which details the fate of humanity from 2140 to 4432. It was written by the lead game developer, John Bergman. The backstory is written from a historical perspective, from the viewpoint of an Itani monk chronicling the events leading to the galaxy's present state. It outlines drastic advances in the fields of medicine and biotechnology during political unrest and warfare on Earth, the discovery of a stable wormhole near Saturn leading to a solar system across the galaxy, and the subsequent exploration, colonization, and inadvertent exile humankind experiences as a result of the wormhole's collapse.

The three national factions are described in great detail, including their origins, personality, and notable historical figures. Subterfuge, misunderstanding, and betrayal are common themes throughout the backstory.

Vendetta Online's development team is relatively small compared to many other titles in the same genre, at its largest including four people. The four original developers are John Bergman, Ray Ratelis, Andy Sloane, and Waylon Brinck. John Bergman remains the managing director and has invested much of his own personal finances into the project. The game is based in Milwaukee, Wisconsin and has been in development since 1998.

In April 2002, the game opened with a public alpha test to prove the efficiency of the twitch style combat in the low bandwidth environment of that era. In November 2004, the game launched as a retail product, with the Linux mascot featured as part of the game box artwork. The retail-CD included Mac, Linux, and PC native versions of the game.

Upon initial release, Vendetta Online received mixed reviews. GameSpot's 2005 review rated Vendetta as "good", highlighting the novel twitch-based space combat, and a successful implementation of multiplayer space trading and combat gameplay. However, it was felt that the limited content did not justify the subscription value, and the ship designs were deemed to be uninspiring. A more recent review by Kotaku stated that Vendetta was "a deep game with an intuitive interface" taking note of the port to Android mobile devices.

Macworld called Vendetta "a brilliant online gaming experience, clearly influenced by classic space games Elite and Frontier". Joystiq praised Vendetta's development saying "For active developer participation, Vendetta Online definitely runs near the head of the pack and might even lead it". In January 2013, Darrell Etherington of TechCrunch named Vendetta "The Most Multiplatform MMO Game Ever".
