A Escola Técnica de Eletrônica Francisco Moreira da Costa (ETE FMC), em Santa Rita do Sapucaí, está sob ataque. Não se trata de uma falha comum, mas sim do Cipher, um vírus nascido dos erros de programação de um projeto ambicioso, que agora se tornou uma ameaça digital consciente e descontrolada. Ele não só corrompeu os sistemas, como também sequestrou os próprios criadores do projeto, alunos com profundo conhecimento técnico da instituição, puxando-os para dentro de um mundo virtual caótico e cheio de bugs. Nesta aventura eletrizante, você assume o papel de Kai, um aluno que chega à escola no momento exato do colapso. O pânico domina, mas a missão é clara: salvar seus amigos! Ao encontrar o Arcade misteriosamente ligado, você descobre que a única forma de resgatá-los é controlando-os dentro do pesadelo digital. Prepare-se para mergulhar em cenários transformados e corrompidos pelo vírus. Locais conhecidos da cidade e da ETE são distorcidos em fases de puzzle e combate que exigirão toda a sua sagacidade. Decifre códigos complexos e restaure lógicas de programação. Reconecte fiações e reorganize sistemas eletrônicos com precisão. Enfrente anomalias digitais poderosas, como o caótico Junk-o e o enigmático Glitch, que exigirão estratégia e rapidez para serem desativados. Cada fase é um teste às habilidades técnicas dos alunos, e o sucesso em cada desafio é um passo vital para trazê-los de volta à realidade. A narrativa envolvente explora as especialidades de cada personagem, transformando o conhecimento técnico em ferramentas de gameplay. O destino dos alunos, a segurança da ETE FMC e a contenção do vírus Cipher dependem de você. O tempo está correndo e os bugs estão se espalhando. Você está pronto para navegar pela falha de sistema e reverter o ERROR 503? Entre no Arcade e comece a restauração!
