6. House of the Dead
The House of the Dead was a lightgun game released by Sega and the series itself has gained a lot of critical acclaim throughout the years. You controlled AMS Agent Thomas Rogan who receives a distressing phone call from his fiance Sophie who works at the mansion of world renowned biochemist and geneticist Dr. Curien. Rogan, together with his partner G go to the mansion to investigate, only to find that the entire place has been overrun with zombies and other creatures. The game was challenging due to the player only starting off with three lives which you lost by either being attacked by enemies or shooting a civilian- though these lives could be gained back by saving civilians or finding lives hidden inside boxes.
