Terms & jargon

Sudden Attack Zero Point Glossary

This Sudden Attack Zero Point glossary defines the terms you will hear in the lobby, the buy menu, and voice comms across the 5v5 Bomb Defusal and Team Deathmatch modes of Nexon's tactical FPS remaster. It covers round economy words like eco and full-buy, the game's signature 200+ part customization vocabulary, the confirmed KRISS Vector, the Prime character system, and the Black Market trading loop built on SP, Key Cards, and Crates. Definitions stick to what Nexon has shown through the Final Closed Beta rather than the full launch roster.

Bomb Defusal: The signature 5v5 mode (also called Explosive Mission), where an Attack side plants the C4 and a Defense side prevents or defuses it across round-based play with no health regeneration. The Final Closed Beta ships four Bomb Defusal maps.
Attack side: The attacking team in Bomb Defusal, whose objective is to carry and plant the C4 at one of two bomb sites, then hold the plant until detonation. Winning the round requires either a successful explosion or eliminating all defenders.
Defense side: The defending team in Bomb Defusal, tasked with stopping the plant or defusing the C4 once it is placed. Defenders win a round by running the clock out, defusing the bomb, or eliminating every attacker before the plant.
Bomb site A/B: The two designated plant locations on every Bomb Defusal map, conventionally labeled A and B in FPS shorthand. Attackers pick one to plant the C4 while defenders split coverage between them; rotating between sites is the core tactical decision each round.
C4: The plantable explosive the Attack side carries in Bomb Defusal. It is the only piece of gear in the game that cannot be customized with parts, unlike primary, secondary, and melee weapons. Detonation at a bomb site wins the round for the attackers.
Eco round: A round where a team deliberately spends little or nothing to save currency for a later full-buy, a standard tactic in round-based Bomb Defusal with no health regeneration. Players ride out an eco with starting pistols and minimal gear to bank for stronger loadouts.
Full-buy: A round where a team spends up to buy primary weapons and full equipment after banking through an eco. In a mode without health regen, coordinating full-buys so the whole team is armed at once is central to winning the economic battle across rounds.
Weapon parts: The functional attachments at the heart of SAZ customization. There are 200+ exclusive primary parts plus 36 shared parts, fitting slots such as scope, grip, magazine, underbarrel, muzzle, barrel, handguard, and stock. Parts change recoil, reload speed, and appearance, so one gun feels different per build.
Gunsmith: The common FPS term for the loadout screen where you fit parts into a weapon's slots: eight on a primary, five on a secondary, and two on a melee (blade and handle). Skins added here are cosmetic only, while parts alter handling stats.
KRISS Vector: The one weapon Nexon has confirmed by name for SAZ, quoted from its in-game description as a submachine gun. The Final Closed Beta arsenal totals 13 primary and 4 secondary weapons, though the rest of the named roster has not been officially published yet.
Prime character: A premium 'Prime Funny Character' cosmetic model, reworked from the original franchise, that bundles passive utility functions rather than Valorant-style abilities. Functions include jump-sound mute, grenade-radius warning, footstep-volume reduction, hit markers, and minimap enhancements. The beta features 10 playable characters with different trait subsets.
Black Market: The player-to-player trading hub where earned weapon skins, parts, attachments, and items change hands. Because functional parts are tradeable, the Black Market affects real loadout power, not just cosmetics. A 'Black Market Event' ran during beta before all beta items were wiped.
SP: An earnable soft currency awarded through play and events. Players accumulate SP alongside other beta rewards, and skins can also be earned by reaching max weapon mastery. No named premium hard currency has been published, and a battle pass is not confirmed.
Key Card: An item used to open Crates in the SAZ economy. Key Cards are earned in-client through missions and events rather than entered as a code, since the pre-launch game has no redeem or coupon system. They pair with Crates to deliver skin and part rewards.
Crate: A chance-based container opened with Key Cards, including the 'Epic Skin Parts Crate' awarded from Match Victory. Crates are the loot-box mechanic disclosed on the Steam page, dispensing skins and parts. Because parts are functional, crate contents can influence loadouts, not only looks.
Team Deathmatch: The 5v5 TDM mode where the first team to reach the kill target wins, played on small close-quarters maps in the beta. The Final Closed Beta pairs two CQB maps for TDM with four larger Bomb Defusal maps, giving a faster, respawn-driven alternative to the objective mode.
Callout: A spoken location name teammates use to report enemy positions, such as a bomb site or a specific angle. Since Nexon has not published individual SAZ map names yet, community callouts are still forming; clear comms remain essential in a no-regen mode where information wins rounds.
CQC: Close-quarters combat, the short-range fighting that dominates the two small CQB maps used for Team Deathmatch. Fast SMGs like the KRISS Vector and mobility-focused part builds suit CQC engagements, where reaction speed matters more than long-range accuracy tuning.
Anti-cheat: SAZ runs Nexon Game Security, a kernel-level anti-cheat that loads at the driver level to detect tampering. Kernel-level protection is why the game and its betas require Windows and are region-locked, and it reflects Nexon's push to keep the competitive FPS environment clean at launch.
Remaster: SAZ is a remaster, not a sequel, of the 2005 Korean FPS Sudden Attack, which Nexon bills as 'beloved for 20 years.' The remaster rebuilds the classic Bomb Defusal formula for a global, free-to-play audience, adding deep weapon parts customization and the Prime character system.
