About
Deep within a top-secret underground facility on floor B9, you have successfully developed the vaccine for the zombie virus. Immediately after, the facility is overrun by the infected. Your mission is clear: Protect the vaccine and reach the rescue helicopter on the surface.
Minus Nine is a survival shooter that combines classic arcade action with the strategic depth of a roguelite, presented in a Top-down Isometric View.
Explore to Survive Your journey begins at -9F. The layout of the facility changes every run through procedural generation. Utilize the isometric perspective to plan your route and locate hidden Generators in the dark. Only when full power is restored will the elevator gates to the next floor unlock.
Strategic Combat & Upgrades Ammo and health are scarce resources. Eliminate the zombie hordes and extract "Bio-Samples" from them. Use these samples at the Rest Area—the elevator between floors—to upgrade your Damage, Health, Ammo Capacity, and Speed.
Death and Rebirth Death is part of the process. If you fall to the infected, you will lose your gear and wake up back at -9F. But do not give up. Your skills and experience are the only keys to escaping this hell.
Procedural Generation: A constantly changing labyrinth with randomized enemy spawns.
Isometric Action: Tactical top-down gameplay that requires precise aiming and positioning.
Upgrade System: Enhance 4 core stats (Health, Damage, Ammo, Speed) using Bio-Samples.
Intense Atmosphere: Dark underground environments, dynamic line-of-sight mechanics, and immersive sound design.

Fun game to mess around with, if it's still being updated I would recommend making the bio capsules drop on death rather than despawn since it impairs the pace a bit.
짧게 적습니다. 개발자님. 적이 너무 많아서 진행을 못하겠어요. 적 체력도 높고 숫자도 많아서 총알 다 떨어질 때 까지 쏴도 계속 튀어나와요. 8층을 못 깨겠습니다. 무기가 재장전 할 때 마다 랜덤으로 바뀌는건 일부러 의도하신거 같은데요.. 적에게 둘러쌓인 상태에서 바추카포가 나오면 그냥 죽으라는 말이 됩니다.ㅠㅠ 수정이 필요합니다.
Oyunda, Aşıyı güvence altına alın ve istila edilmiş tesisten kaçın! Bu izometrik roguelite nişancı oyununda B9'dan yüzeydeki kurtarma helikopterine kadar savaşarak ilerleyin. Gücü geri kazanın, ekipmanınızı Biyolojik Örneklerle yükseltin ve insanlığın son umudunu bitmek bilmeyen enfekte dalgalarına karşı koruyun.

Просто дешевая поделка, задумка хорошая и геймплей мог быть интересным если бы не скучная музыка, странная графика и примитивный геймплей. https://youtu.be/8jWa2-dlJpY
게임이 너무 어려움.. 업그레이드한거 죽으면 다 초기화됨.. 총알을 안주고 무기 한개 다 써야 다른 총으로 넘어가는 시스템임.. 몹이 계쏙 리젠되고 몹 체력도 높고 너무 많음..
good game to pass time and really entertaining
More tedious than fun. the gun swapping just adds 5 guns that are unusable in later stages, forcing you to empty your entire gun if its not a flamethrower, and the endless zombies spawning in from every corner is just plain ♥♥♥♥♥♥♥♥. either let the player see the zombies wherever they are, or add in designated spawn locations so its actually possible.
