I've always felt that the ZAPT gamemode could've used a Spitter zombie (named the Hocker). There are images referencing to a Spitter in the mod's files, however, it appears as if it was scrapped for some unknown reason. But is it possible to add new zombies in ZAPT? If so, then I would love to see a Spitter be placed in the game.
(Not sure if this went in the right board).
