Jedi Knight: Arena (JK:Arena) is a  Total Conversion for LucasArts Jedi Knight: Dark Forces II. Like other recent first-person shooter games, JK:Arena will be completely multiplayer-based with the option of using ai controlled bots (using RBots technology) in single player mode. The gameplay of JK:Arena is very much the same as Jedi Knight, with a few tweaks and enhancements. There will be several new game modes, weapons, items and Force powers. Much of JK:Arena will be influenced by feedback from the Jedi Knight Community.

The idea here is to dominate (duh!) a certain number of key locations for a set amount of time. The first team to achieve the required amount of points wins!

Instant Kill:
This is the style of game you should go for if all-out action is what you're after. Each player wields an Enhanced Stormtrooper Rifle that fires a bolt of of blue energy spelling instant death to its target.

Last Man Standing:
This mode is similar to the regular deathmatch. It defers in that instead of setting a time limit that must be reached in order to win the game, each player starts off with a set amount of lives and all weapons. Each time you die, you loose a life. When a you  loose all your lives you are eliminated from the game. The last man standing wins the game.

Perfect Sword:
This is a quick style of game in which you wield your trusty Lightsaber to duel your enemies. When you die, you are eliminated from the game. The last man standing wins the game.

Retrieval:
This mode is similar to Capture-the-Flag in the fact that you have to capture a flag and return it to your base. The will be three flags in each level, which your team must return to you base. When a team owns all three flags, they win the game.
