"The Engineer" is a middle-aged man from Bee Cave, Texas with 11 Ph.D.s. His main use is to make buildings. His first building, the Sentry Gun, is a non-moving gun that targets enemies and shoots automatically. It can be improved to have more health and firepower. His next building is the Dispenser, which gives his nearby friends health and ammo. Finally, he can also build teleporters, which can move his friends closer to the fight. The Engineer also has a shotgun, pistol, and a wrench to defend himself. His Sentries are great for stopping anything short of an Übercharged player. The Engineer himself is weak, and poorly placed Sentries can be blown up by smart Soldiers and Demomen. Spies also ruin the Engineer's day.
