I remember that once, my mom had an old PC, around the year 2013, 2014, 2015.
There was an old game that I remember only a little about.
In this game you had to protect your house from some zombies, but your character stayed on top of his house shooting the zombies so they wouldn’t get into the house.
I remember that the game was browser-based.
Plants vs zombies??
it seems to be some game from The Last Stand franchise
