정예81탄 마지막에 엘리트보스 나오고 잡고나서 어차피 마지막이니까 카드 암거나뽑고 스테이지 클리어 되야하는데 몬스터는 없고 클리어도 안되고 그상태로 그냥 전투 나가기 해야합니다 클리어하는 기점이랑 카드 나오는 기점이 맞물려서 버그 인거같아요 81탄 연속2번째 다 깨놓고 전투포기하고 나왔네요

isn’t functioning on my phone can’t login

### 4/5 — O jogo é bacana masssss

*2026-06-30*

O jogo é bem bacana, tem uma fluxo de progresso contínuo mas anteriormente existia uma possibilidade maior de conseguir as slim de armas, do personagem principal e dos ajudantes mais fácil e de forma gratuita hj é praticamente impossível se não pagar. Que torna o fluxo de jogo sem benefícios e muitas vezes até sempre a mesma coisa! Melhorem isso que o jogo vai ficar top

**Developer response:** Agradecemos por jogar nosso jogo. Confirmamos sua preocupação sobre a dificuldade em obter itens de personagem e arma gratuitamente. Suas sugestões foram confirmadas e compartilhadas com a equipe. Obrigado novamente.

### 4/5 — Ban the hackers

*2026-06-27*

Over the past couple weeks there’s been at least one guy, maybe more, who’ve figured out how to cheat the system and get any upgrades they want. It’s ruining game play for everyone else.

**Developer response:** Thank you for playing Bunker Defense: 100M Survival. We have confirmed your discomfort regarding the presence of hackers. For inquiries, please use the in-game 'Contact Us' feature. Thank you again for your valuable feedback.

### 5/5 — Best and addicting game

*2026-06-05*

Honestly the best game I’ve ever played. Very complex and long playtime. I have a suggestion for developers- how about merging the gears to increase level of gears? If I have 3 T4 gears, why can’t I merge them to get a T5 gear? Think about it and let gears merge like other chips. Thanks.

**Developer response:** Thank you for playing Bunk Defense. We deeply appreciate your detailed suggestion regarding gear merging. We have confirmed your suggestions and will share them with the development team. Thank you again for your valuable feedback.
