Academia Z: The beginning of the catastrophe

A third-person action video game set in a post-apocalyptic world of zombies in an anime style.
The world has been ravaged by a zombie apocalypse. Emilia, along with her friend and other students, will try to stay alive within the educational center while zombies lurk around every corner.
Waiting for help won't be the best option. The scarcity of medicine, food, and water will force them to venture outside as they seek help, but nothing will be so simple. They will encounter a city looted by other survivors, who, faced with the lack of resources, will opt for more ruthless actions.
Emilia and her companions' mental health will be threatened, facing psychological and emotional problems as they try to find moments of happiness in a desolate world, although happiness is fleeting in this dark and hostile world.
Will they be able to overcome adversity and preserve the remaining humanity, or will they succumb to the bleak fate that seems inevitable in this new post-apocalyptic world?
