NULL VECTOR

NULL VECTOR is a top-down survival tower-defense game built from neon geometry. Defend the central core while directly controlling an operator unit: move, aim, fire, and deploy active skills before enemies break through your defense.

BUILD YOUR DEFENSE

Research core, operator, and system upgrades. During preparation phases, place fortifications and adjust weapons, active skills, and passive bonuses. Enemies can carry combinations of shields, healing, dashes, splitting, ranged attacks, and many other abilities, forcing your strategy to evolve.

COLLECT ABILITY MODULES

Defeating ability-bearing enemies can drop their corresponding modules. Equip a limited set of modules to combine movement, ammunition, defense, control, and resource effects into your own build. Discovered modules are permanently retained by your operator.

CAMPAIGN AND ENDLESS DEFENSE

Fight through a 15-wave solo campaign with a special boss on Wave 10 and a final boss on Wave 15. Complete the campaign to unlock Endless Mode, where enemies scale without limit, carry randomized ability combinations, and unleash a boss every 10 waves.

COOPERATE WITH UP TO FOUR PLAYERS

Defend together in online co-op. Multiplayer uses a separate 30-wave run with shared construction costs, a visible loot pool, end-of-match distribution, and enemy and boss counts that scale with the number of players.
