Gun Z: The Duel - Gameplay

Gameplay

In Quest mode, players, in a group of up to 4 members, go through parts of a map for a certain number of stages, which are determined by the quest level. In each stage, players are required to kill 20 or 26 creatures, and the game ends when every member of the player team dies or completes all of the stages. Quests can take place in the Prison, Mansion, or Dungeon map.

Players can make the quests tougher and more profitable by using special quest items to increase the quest level that can be bought from the in-game store or obtained during a quest. Quest items in-game are stored in glowing chests that spawn where the monster that it came from died; certain items may be dropped depending on the monster killed. Players run through these to obtain an item randomly selected from the possibilities of that monster. The items obtained depends on the monster that the chest came from. By sacrificing certain items in combination, players can enter a boss quest. Boss items are obtained through pages and other boss quests, and pages are obtained through the in-game shop. The quest system was designed to reduce the amount of time needed to prepare for boss raids that are typical in many other online games.

A significant and unique part of the gameplay is the movement system. Players can run on walls, perform flips off of them, and do quick mid-air dodges in any direction. Advanced movement and combat techniques are commonly referred to as "K-Style" or Korean style; a variety of techniques fall under this category. These usually exploit the game's animation and weapon switch systems through a series of animation cancellations to allow the player to perform another action rapidly after the first. One example is the wall cancel; unlike the normal slow method of running on walls, the player can simply jump, dash mid-air in the direction of the wall, and upon hitting it slash or stab with their melee weapon. This will cause the player to gain height with each successive timed dodge-slash, and it is possible to stay in the air near walls and travel along them indefinitely using this method. This, in addition to the fact that these techniques are possible as a result of exploiting flaws in the animation system, has resulted in them being controversial but they have become largely accepted as part of the game. The forthcoming sequel to GunZ will reportedly retain some of these K-Style features, though they may be implemented differently.

GunZ's networking system in most parts of the game is peer to peer. Players connect to other players through their client, instead of through a central server.
