Hyprnull is a frantic first-person arena score-attack where your life is a countdown. Swarms of enemies. Towering bosses. One clock. Kill to stay alive, chain kills to climb, and take on the arena alone or with up to three friends.
OUTRUN THE CLOCK
There is no health bar. The countdown is your life. Kills buy time. Hits cost time. When it reaches zero, the run is over. Stop moving and the arena will finish you first.
SCORE TOGETHER
Invite up to three Steam friends into online co-op. The squad shares one countdown, one multiplier and one score: a kill by anyone buys time for everyone. Each player brings their own loadout, so you can cover each other's gaps. Co-op is by friend invite only, with no matchmaking.
SWARMS AND BOSSES
Every enemy demands a different answer. Some rush you in packs, some strike from the air, some attack from range, and some throw crates you can knock straight back at them. Then a boss arrives and the rules change: the clock stops and becomes your life, and nothing buys time back until the boss falls.
MASTER YOUR LOADOUT
Pick your weapon and ability before the run. Once the fight starts, your kit is locked in and mastery is all that's left. Every weapon is its own playstyle. The Katana builds Flow through relentless hits and spends it on a Dash Slash through the crowd. The Hammer is slow, heavy and brutal. The Spear mixes combos with ranged attacks. Unlock new weapons and arenas as you play.
USE THE WHOLE ARENA
Slide under danger. Wall run past the horde. Grab crates and throw them through the crowd. Speed feeds your score, and the arena is as much a weapon as your blade.
CHASE THE SCORE
Movement, clean hits and kill chains drive a five-tier multiplier. Land special kills for bonus points, earn a rank from D to S, and climb the online leaderboards. The clock ends every run. The number is what you leave behind.
