From the Homepage:
“Gloomy Nights and Living Dead” is an oldschool arcade action game that will remind you of the good old days. If you were a zombie hunter back then, it will have an even stronger effect of nostalgia on you.
To win the game, you simply have to beat 100 levels. To master this, you’ll just have to turn all the living dead into dead dead. In other words… just shoot at everything that moves!
Sounds hard? Well, if you don’t feel capable of doing this all by yourself, you may also ask a fellow human for assistance.
