Dead Age

The best place to find Bitten Pedestrians is on Highway Day/Night. The Highway, both Day and Night versions, are available right at the start of the game. Because Bitten Pedestrians are one of the earliest enemies encountered in the game, this may be the first "Kill 10" achievement you will unlock.

Only zombies labeled as "Bitten Pedestrian" count for this achievement.
