Miscellaneous Units

Noncombatant units

You can't win with just these guys (well, you could) but they are essential or helful.

Settlers. The old reliable settler. No new improvements here.

Engineers. The enginners ROCK! These guys are awesome. They become available
xxxxwith the discovery of explosives. They are a super settler. They can build faster and
xxxxcan transform terrains, from say hills to grassland.

Explorers. These guys become available with the discovery of seafaring. These are nice
xxxxxxsince they treat all terrains (even mountains) as roads, so they can move 3 squares per turn.

Caravan. Nothing new here.

Freight. The modern version of the caravan (camels just don't make sense in the
xxxxxxxxindustrial age). Becomes available with the corporation. Can move two squares.

Diplomacy units.

Diplomat. The same old guy, with a few twits. Now, you don't have to send one out everytime
xxxxyou want an audience (if you have an embassy). Foreign nations can also expel your diplomats.

Spy. The modern diplomat, it becomes available when you discover (what else) espionage. It has
xxxxmany useful powers such as bribing units, sabotaging units, stealing specific technologies and more!
