On Adam Jensen's first visit to Detroit, the majority of the convention center is gated off, and thus relatively unimportant. However, a few thugs are hanging out in the vestibule and will engage Jensen if provoked. A possible explanation for these thugs relatively hostile nature is a TMP-18 stashed within a nearby air duct. It is accessible through vents located near the back of either bathroom, or by jumping on top of a vending machine, the latter likely requiring the Jump Enhancement augmentation.
