(Capcom's primary storyline)
Austin Taylor was a watchman at the Raccoon Zoo. His job was to handle dangerous animals and difficult tasks regarding the day-to-day operation of the zoo.
The player can talk to him in the Zoo's Observation deck where he barricaded himself. He will ask Cindy Lennox to let his remaining comrades know that he is safe. According to a file found, Austin is the owner of the Hunting Rifle found in the Observation deck.
It may be possible he survived the Raccoon Zoo incident at least due to Patrick and Lloyd commenting on how he could handle the current situation when the player talks to them after talking to Austin. However, this is unconfirmed.
Austin is unlocked as playable by talking to his NPC on HARD or VERY HARD, and then talking to either Patrick in the Elephant Stage area and/or Lloyd in the zoo's Inner office. The player does not have to beat the scenario to unlock him, but has to fulfill the above requirements of talking to Austin before the other two. As an NPC, Austin only appears on the harder difficulties of wild things - he will not be encountered on the EASY and NORMAL. After fulfilling the requirements, he can be purchased in the Collection menu for 4000 points.
