Another returning hero from Team Fortress Classic, the Well map, has had a similar aesthetic overhaul, and now sports a train yard where previously there was none. On top of this, it's also become a control-point map, with a linear series of points that must be captured in order. As an Engineer, we found ourselves placing teleporters to move our teammates forward more quickly. Turrets were built, upgraded and repaired using metal found in guns and ammo on the battlefield, and dispensers were constructed to shovel ammo and health into the needy hands of other players on our team.
Part of the challenge of being an Engineer is placing turrets in the right spots - too far behind the combat and they're no help, too far forward and they're impossible to repair or upgrade without taking one between the eyes. All the while, information on the objects you build will appear on the HUD, telling you not only when they need repairing, but how much they're being used. And yes, seeing ten people use your teleporter really does make you feel loved.
