Call of Juarez uses Techland's Chrome Engine 3. There are four difficulties, Easy, Normal, Hard, and Very Hard, the last being unlocked after the game is completed. Gameplay is nearly completely combat oriented, and both main characters have different combat styles. Reverend Ray is tougher, can use dynamite, dual wield revolvers, or fan a revolver which serves as a rapid-fire method. In addition he can also kick to injure opponents or open doors, and either hit or throw chairs at enemies. Billy Candle is more fragile and is associated with stealth, often having to perform tasks where the player cannot be seen by NPCs (such as retrieving a saddle to ride a horse) or else the mission is failed. He can also use the whip to traverse areas that would otherwise be unreachable, and use the bow. There are many instances of exploration and adventure as Billy Candle, which are reminiscent of Indiana Jones, especially because of his use of a whip. More experienced players can be more direct in their approach and fight up-front like Ray as Billy if they choose. In the PC version, both characters have 100 health points, and when lowered enemies will drop vitality which restores 25 points per bottle. This was changed in the Xbox 360 release (which was a port of the PC version) to regenerating health. Available weapon conditions are rusty, normal and prime, though in Very Hard mode prime weapons do not appear. Weapons in rusty condition will degrade when fired and eventually explode destroying the weapon, keeping the player from attacking for a few seconds. The weapon's icon will flash red as a warning this is about to happen.
Both characters have a unique Concentration Mode, an ability that slows down time for a short while, allowing Ray to fire both revolvers in slow motion, and Billy to line up a shot with the bow. During some chapters, the player will engage in a duel with another NPC. A timer counts down, and the player must engage in a simple draw, aim and fire mechanic. A second method of boss fights are fistfights are initiated in the story between the player character and one or more NPCs, this will lock the player to using only their fists until the opponent(s) are dealt with. A third type involves normal gameplay against a character with more health than an average enemy, such as against Tom Manson. Horses are used as transportation in several episodes, and while on horseback the player can fire weapons, unless the horse is sprinting.
When dismounted, walking to the rear of the horse they can be slapped, sending them jolting forward and on some occasions, this will provide a distraction for enemies. Notably corpses, horses and NPCs cannot be harmed, Ray or Billy will turn their weapon away and provide a comment about the situation. There are ways around this, although most result in mission failed. To kill a horse, Billy or Ray have to ride up on the edge of a cliff and ensure they get off the horse (else they will die as well) sometimes the steed will gradually fall, but most of the time the player has to use the "slap horse" option to get the mount to rear up and plummet. Also, you can set a fire and let the horse burn. These two methods are the only ones that do not result in mission failed. To kill NPCs, you can throw dynamite near them as Ray, or back up and aim above them using the bow as Billy, or whip them in the head also as Billy, but all result in game over.
There are four classes to choose from and seventeen maps. There are four game modes:
Deathmatch - A traditional deathmatch mode, where it is every man for himself. The player with the most kills at the end of the clock wins the match. All players appear as Apache.
Skirmish - A team-based arena mode between Lawmen (Blue) and Outlaws (Red). All players have one life, and the objective of both teams is to eliminate everyone on the other while of course, staying alive.
