What is KS Z?
KS Z is a first-person tactical shooting game created by NOT_Lonely that pits red and blue squads against each other in fast round-based firefights. Players coordinate movements, manage ammunition, and secure objectives across four distinct 3D battlegrounds. Unlike standard arena shooters where eliminations are the only objective, this title lets participants disarm opponents and capture prisoners to shift match momentum. The entire experience runs directly inside your web browser without requiring client downloads or account registration.
Key features
- Two competing factions: Enlist with either the red or blue squad, each outfitted with distinct starting armaments.
- Five match types: Compete across Teams, Bomb, Deathmatch, Zombies, and Free-for-All match formats.
- Subdue opponents: Strip rival combatants of their firearms and take them captive during close encounters.

Prisoner capture and loadout management
A distinct mechanic in KS Z is the capacity to disarm opposing fighters. When cornering an adversary at close quarters, players can press the interaction prompt to confiscate their gun rather than immediately eliminating them. This subdues the rival, takes them captive, and deprives their team of an active gun on the field. Captured adversaries also drop their equipment, allowing you to salvage valuable supplies without spending team currency.
Weapon variety is similarly substantial, offering 17 weapon types distributed across team inventories. Players can equip primary rifles, backup sidearms, and three tiers of thrown explosives assigned to numerical hotkeys. Cosmetic skins let you modify weapon finishes before matches commence. During prolonged firefights, activating a timed boost using the designated perk hotkey provides an edge during critical skirmishes.
Tips and strategy
- Use slow walking near corners: Creeping with the walk modifier silences footsteps so opposing squads cannot track your patrol path through audio cues.
- Crouch to stabilize bullet spread: Lowering your combat stance reduces recoil when firing sustained bursts down long corridors.
- Conserve thrown explosives: Save your grenade slots for clustered squads defending tight chokepoints or guarding objective zones.
- Subdue rather than shoot when flanking: Taking a disarmed foe hostage removes them cleanly while securing their loaded firearm for your own inventory.
- Coordinate around faction loadouts: Red and blue squads possess distinct weapon selections, so adjust your engagement ranges to suit your faction gear.
Game modes
Teams
Two organized squads clash over round rounds, working cooperatively to eliminate opposing combatants or clear designated map objectives.
Bomb
One squad attempts to position and detonate an explosive device at a target site while defenders set up perimeters to disarm the package.
Deathmatch
Combatants engage in fast-paced respawn matches where the roster race to accumulate individual and team frag counts before the clock runs down.
Zombies
Fighters fend off relentless hordes of infected threats, managing ammunition reserves and falling back to fortified defensive corners.
Free-for-All
Every combatant fights independently without faction alliances, requiring quick reflexes and constant radar vigilance across all four combat locations.
