Cube is a free and open-source first-person shooter video game. It often is mistaken with its engine (zlib-licensed), the Cube Engine. The engine and game were developed by Wouter van Oortmerssen. It runs on a variety of operating systems, including Microsoft Windows, Linux, FreeBSD, OS X, AmigaOS 4, AROS, iPhone, Wii and Pocket PC devices with 3D acceleration such as Dell Axim x50v. It uses OpenGL and SDL. Cube has both single-player and multiplayer gameplay. The game contains a built-in level editor. The game was originally released in 2001. The first release with single-player mode was in January 2002. The latest update of Cube was released on August 29, 2005. It's engine was reused for several other games. AssaultCube, released in November 2006, is the most popular of them. An official successor has been made called Cube 2: Sauerbraten (also simply known as Sauerbraten). Released in 2004, it uses an other engine, the Cube 2 engine. Gameplay As of the August 29, 2005, release, there were 37 single player maps and 65 deathmatch maps, for a total of 102 maps. Multiplayer uses a networked game code and a thick client/thin server model. Single-player The single-player game play includes two modes. A plain single-player mode in which items and monsters do not respawn and have a fixed position; and a deathmatch-style mode (where there is a fixed number of monsters, ten per skill level) and items respawn. Multiplayer Multiplayer gameplay includes twelve modes: "Free For All": Non-teamplay, meant for free-for-all and duel games. This mode is often used for prewar and setting up teams. "Coop Edit": Players can edit maps offline or online with others simultaneously. "Teamplay": Like Free For All, only allied with those whose team variable is the same as the player's. "Instagib": All players spawn with full rifle ammo and 1 health. No items are available (non-teamplay and teamplay). "Efficiency": All players have two ammo packs each with 256 health (non-teamplay and teamplay). "Insta Arena": When fragged (killed), players stay dead until there is only one player remaining, and then a new round begins; each player only has the rifle and fist (non-teamplay and teamplay). "Tactics Arena": Like Insta Arena, but each player randomly gets two out of the four possible weapons (with fist), and two ammo packs each (non-teamplay and teamplay). Development Game engine The Cube engine was designed as an outdoor engine, i.e. it's designed for
