What are some good games like the Crazies?
>enemies are infected by something or driven insane but retain enough sapience to use tools and utilize basic tactical thinking, rather than mindless zombies just trying to swarm the player to bite/swipe at them, but also more typically focused on killing the player vs self-preservation
>MC is on his own but is more resourceful, has better weaponry and guile

Resident Evil 4 is the most overt example with Leon being a gunslinging secret agent battling his way through a farming village and a castle and fending off the villagers using rudimentary implements and bows with guns, with the village even having a few Straw Dogs-esque showdowns as Ganado try to break into the house.
