Engineer is a class in Team Fortress 2. Engy's arsenal includes: A Shotgun, a Pistol, a Wrench, a Construction PDA, and a Destruction PDA. With the Construction PDA, you can build 3 different buildings (none of them can move on their own): A Sentry Gun that shoots enemies, a Dispenser that heals and gives ammo to teammates, and a teleporter which can teleport your teammates to the teleporter exit. Your buildings can be built with metal, which can be gotten by normal ammo packs, and the max ammo you can have is 200. You can repair, refill, or upgrade your buildings with metal, too. You can build your buildings faster, repair, refill, and upgrade your buildings by hitting them with your wrench. You can destroy your buildings with your destruction PDA. Engineer's playstyle consists of supporting and defending your team with your buildings.
