Irvine is a secret location in Wasteland 2.
Appearing on the map only after pushing the red button in the Hollywood Sewers, Irvine is the most simple town location of the game. Consisting of exactly one NPC and no other location within the town, you will spend more time reading this entry than interacting with all of Irvine.
There are 3 possible dialogue options with Aaron Schwab, each requiring a skill. None of the Hard Ass, Smart Ass or Kiss Ass option will lead to anything other than the XP for successfully using the skill.
