Western Quake III is intended to be a realistic simulation of the "Old West's" great atmosphere. It is being developed - as you can see in the name - on id Software's Quake³ Arena Engine.

This Total Conversion will include completely new weapons created with historically correct information about damage, rate of fire, reload time etc. It will also include new gametypes and maps inspired mostly from movies. And to increase the feeling of "Gunslingers Atmosphere" we will also create music tracks and sounds adapted to the simulated times and according to the era.

The Gametypes
All game modes are based on the prize/reward system. Prize/Reward means you get money for kills, with the money being used to buy weaponry, ammunition and special items. The system is weighted so those "better" players are worth more reward money than novices.
"By killing a player with more kills than you have, you will get more money than he would earn for killing you."
The sentence above demonstrates to you the basic idea of this system: The bad players won't become worse due to the lack of money for weapons, so fair and balanced gameplay is possible. So even if you don't get a lot of kills you can make the ones you do get count!

Bank Robbery game type:
As the name says the goal of this game type is robbing the bank. One team has to attack the bank and steal the "money bag". The robber's team is equipped with triple dynamite, which allows them to blow a hole in the building and proceed to the money. After grabbing the money, they just have to head back to the escape point with it to win.
Robbing the bank isn't going to be easy because the whole second team is protecting the bank and will try to prevent the other team from getting in. While a robbery might be more difficult to pull off, it will be much more profitable than just killing off the defending team.

Duel game type:
The idea of duel is to enable classical western shoot-outs using only pistols. This game type is suitable for 2, 3 or 4 players and also for 2 player teams.
The duel maps are huge maps divided into several parts. Separate Duels can be performed in each part of the map (up to 16 players are supported per map). The details of the duel are as follows: The combatants stand opposite each other while a musical clock starts to play. When the music stops the duel begins. The holstered pistols have to be drawn, it will take a few seconds until one can aim precisely (this will be indicated by the crosshair gradually fading in). During this time the player can decide whether he wants to face his opponent (with poorer chances to hit) or seek cover.
The winner of the duel gets money for his kills and usually stays on the map part he "won" where he will meet the next challenger(s).
As you can see, it depends on the amount of players on the server on which map and with whom you play (it's a complicated system and you'll see how it works exactly when it's finished).
