Depending on the character class the player selects at the beginning of the game, the style of gameplay varies greatly. The warrior characters are able to equip nearly all armour and mêlée weapons available in the game but cannot use bows, staves, or magical spells. They do have five spell-like special abilities but instead of using up magic points like the other classes' spells, they recharge over time. The conjurer class specializes in conjuration of various monsters found throughout the game, healing himself and his allies, and the use of bows and crossbows. They have a smaller array of spells than wizards but can summon monsters they've learned about from items called "Beast Scrolls". Alternatively, they can tame wild animals and monsters into following and fighting for them. The wizard characters are very limited in equippable weapons and armor and have very few hit points but can learn the largest array of magical spells, which they can use not only to kill enemies, but also to teleport themselves, to become invisible, and to heal themselves and their allies. Owing to its origins as a multiplayer magical combat simulator, the magic system is complex and allows for spell combinations and traps, inspired by Magic: The Gathering.
Weapons in the game come in many varieties and largely restricted to certain classes: most melee weapons and a few ranged weapons can only be used by warriors; bows and crossbows, by conjurers; and many magical staves, by wizards. Some weapons have enchantments on them that add magical bonus to the physical damage they deal to enemies. Armor can also have enchantments on it, protecting the wearer from certain types of harm (fire, poison, etc.). With very few exceptions, both weapons and armor wear down when used, so the player must either have them repaired by NPC traders or replace them with new items. At several points of the single-player campaign, non-player characters temporarily follow Jack, either to assist him or to be led to safety by him. These NPCs can be neither controlled by the player nor equipped with better items.
The multiplayer game types are similar to those found in online first-person shooters: deathmatch (further subdivided into "free for all", team, and clan modes), capture the flag, "Flagball" (similar to the "Bombing Run" mode in Unreal Tournament), "King of the Realm", and "Elimination" (deathmatch with limited respawns). The expansion pack NoxQuest introduced an eponymous cooperative multiplayer mode, wherein a player team must navigate through various locations, killing monsters and looting items. Originally, Westwood ran an online ladder ranking system of Nox multiplayer matches and team-based "Clan Matches" but it has since been closed down. The online services of the game were officially replaced by redirecting to the server portal XWIS maintaining the game's online playability; a feature shared by other Westwood Studios Command & Conquer titles.
Plot
Synopsis
The back-story of Nox is explained through location loading screens. Some decades before Jack's arrival to the Land of Nox (the eponymous fictional setting of the game), a group of Necromancers attempted to seize control over the world but was stopped by the legendary hero Jandor wielding an artifact weapon named "the Staff of Oblivion". Following the Necromancers' defeat, Jandor trapped their souls within the magical Orb, which the Arch-Wizard Horvath then transported to another dimension later revealed to be modern Earth. One of Jandor's last deeds of the war was saving a female infant he found in the Necromancers' lair: unsure what to do with a possible Necromancer offspring, he left the girl in the care of an Ogre village. He then disassembled the Staff and gave each piece to one of the three powerful factions in the game: the Fire Knights of the fortress Dün Mir (the Halberd of Horrendous), the wizards of Castle Galava (the Heart of Nox), and the conjurers' Temple of Ix (the Weirdling Beast). After this, he assumed the nickname "Airship Captain", under which he plays a mentor role to the player throughout the game.
