Quake III: Team Arena is the official add-on to Quake III: Arena. It adds a lot of multiplayer game types: Harvester, Overload and One Flag, all focused on team play. There is a selection of new power-ups aimed at introducing a class-based structure similar to Team Fortress. Three new weapons are available: a nail gun, a chain gun and a proximity mine launcher. There is also a batch of new levels, and a few graphical and sonic tweaks like the inclusion of Doppler-shift effects when rockets streak past your head. And finally there is a set of one-use items like Kamikaze (kills you in a colossal explosion, taking out anyone unfortunate to be around) and Invulnerability, which freezes you in mid-air and surrounds you with a near-impenetrable shield.
Beyond Reality II by id Software is a upgraded version of Team Arena level Beyond Reality which was based on the Q3A CTF level Across Space. Created by id Software.
The low down on this map is no more moving platforms from base to base where you get nailed just traveling across the map its all jumps now. Each base has 2 floors to provide cover and more strategy to grab the other teams flag along with a new platform on the side where you can hook yourself up with an extra yellow armor.
