The Engineer (Grant Goodeve) from Team Fortress 2 is a relaxed and intellectual "good ol' boy" from Bee Cave, Texas.
The Engineer can build structures to support his team: a sentry gun for defending key points, a health and ammunition dispenser, and a teleporter. He is armed with a standard shotgun and pistol, and a wrench that is also used to repair, upgrade, and speed up building of his structures. He can also remotely destroy his structures.
