Cordial but unimpressed with bluster or violence, Olin is a valuable member of the Outcast team. She is charged with maintaining and running the various electronics and servers recently discovered inside Bailey's Crossroads Outpost. She seeks to catalog and test all the items within the Outpost complex but has had no luck breaking open the heavy blast door, which she believes leads to a bounty of lost technology.
When questioned about the simulation, she says it was likely developed to train soldiers for the actual liberation of Anchorage. This conflicts with the Outcast outpost terminal entries and other evidence (including evidence cut from the game) suggesting the simulation was developed by Chase following the battle and is intended to be a (potentially inaccurate) recreation, not a training exercise. Details in the simulation itself, such as the soldiers posing for the picture that became the Anchorage Memorial statue and the presence of Vertibirds, also support the simulation's development occurring after the battle.
During the battle with Sibley, Olin may pick up and use the flamer from the armory.
"Don't you know? This sim had to have been one of the most important of its time -- it's the liberation of Anchorage, Alaska from the Chinese. Not up on your history, huh? Back before the world was nuked, the Chinese had invaded Anchorage, Alaska. That really amped things up. Eventually, the Americans went in and liberated the city, but there were heavy losses. This simulation trained soldiers for that engagement!"
