Generator Defense

Generator Defense, also referred to as Network Test One, is a gametype appearing in the Halo: Reach Multiplayer Beta.

Overview
Generator Defense will be exclusively played on the map in Halo: Reach Multiplayer Beta. Overall, the gametype is basically an attack-and-defend type of gameplay. There are only two rounds in the gametype; a total of five minutes in each round.

The defending team consists of three Spartans on top of a well-defended hill, while the attacking team consists of three Sangheili that start at the bottom of a hill and as such have to fight their way up to the generators. There are a total of three defense generators on the map which the Spartans have to defend. At the beginning of each match, several weapon caches will be distributed by a Longsword in different locations on the map; each weapon cache can potentially be a Spartan Laser, a Sniper Rifle or a Rocket Launcher. Each weapon cache will be dropped evenly around the map to allow both teams an equal chance of acquiring them. The defending Spartans will be able to lock the generators down -- hence, becoming invulnerable to attacks -- by pressing "x" near one. The lockdown lasts for 30 seconds and will start a cooldown time after the active time period.

Trivia

 * This is so far the only gametype in any Halo game to feature 3-on-3 gameplay.
 * If this gametype is not well-received by fans, Bungie have said they may remove it in the final game, making it a beta-exclusive gametype.
