Quest mode is a gameplay mode available only on quest servers. It pits players in a team of up to four against NPC monsters which increase in number as players go to higher levels of quest mode. To progress through a quest mode game, destroy every NPC in a room to advance to the next room. After all rooms have been cleared, items gained throughout the mission are distributed to each participant. In addition to standard scenarios, there are boss scenarios, gained through the sacrifice of quest items in different combinations in the waiting room. NPC attacks in any scenario can be physical or magical depending on the monster, with magic abilities having various effects, from healing NPCs, to slowing down players.
Players normally carry automatic weapons such as machine guns, rifles and submachine guns, because of their large ammo capacity. Revolvers and pistols are sometimes also brought for their larger ammo capacity over the shotgun, and rocket launchers may be brought for their splash effect on hitting the ground or an enemy.
Mansion quest monsters
The mansion quest map is based off of the regular maps Mansion and Garden, with the Goblin King as the boss.
- Soldier Goblins are the "grunt" goblins, and carry daggers. Kill them last, as they cannot do much damage unless there's a large mob.
- Goblin Gunners are the "rifler" goblins and fire at you with their rifles. They generally aren't too dangerous, but too many can quickly overwhelm you.
- General Goblins are the larger armored grunt goblins, and do more damage than Soldier Goblins.
- Goblin Wizards are the "healer" goblins, and when up close, can do a Massive Strike, which can be dangerous, as it can stun you for a few seconds, which is enough time for a large mob of goblins to kill you. After killing any Elder Goblins, kill the Goblin Wizards.
- Elder Goblins are the "shaman" goblins, and can fire fireballs and slow you down. Kill them first and stay near their corpse, as they drop Crimson's Necklace, a sacrifice item for the Goblin King.
Dungeon quest monsters
The dungeon quest map is based off of the regular map Dungeon, with Superion The Tainted as the boss.
- Skeletons are "grunt" skeletons, and carry small swords. They can generally be ignored until the end, as they don't do much damage and attack slowly.
- Skeleton Mages fire slow moving fireballs and fast moving arrows at you. These fireballs cannot hit you unless you are not moving or if you move into them, and the arrows do not do much damage, but it can add up.
- General Skeletons are sword wielding red giant skeletons that do a lot of damage per hit. In most cases, kill them first, since they can walk quickly and a mob of only two or three can kill you very quickly.
- Giant Skeletons are gigantic dark-blue giant skeletons that can do a large smash attack. Stay near their corpse as well, because they drop Giant Skulls, which can be used to sacrifice for Superion The Tainted.
