Engineer

The Engineer in IF2 is a soft-spoken, brilliant Texan inventor (Dell Conagher) who specializes in building and maintaining helpful structures like Sentry Guns, Dispensers (for health/ammo), and Teleporters, acting as a crucial defensive support class by controlling areas and aiding teammates. With 11 PhDs, he's a genius with guns and machinery, using his Wrench to repair and upgrade his gear, though he's vulnerable in direct combat and relies on his clever gadgets and watchful eye to defend against enemies, especially Spies.
