Technology level 3
Technology level 3 is the fourth of the Technology level classifications. The defining characteristics of a society having reached TL–3 is industrialization. The development of the external combustion engine, a steam engine, combined with the ability to use machines to work metal and other materials drives all manner of new industries of mass production and manufacturing.
The availability of new power sources for mass production and transportation drives an enormous shift in cultures. Rarely is this transition easy or quiet.

Weapon developments are largely refinements of TL–2 designs, including such features as rifled barrels and elongated projectiles for accuracy and ballistic performance, early experimentation with impact-sensitive compounds as propellant igniters, very crude telescopic sights, and repeating weapons such as revolvers.
By the latter half of this period, almost every soldier would have a rifled single shot muzzle-loading weapon, with a detachable bayonet for melee use if there was insufficient time to reload. Artillery science is slightly more advanced, and crude exploding projectiles are in use by the end of tech level 3, as are are occasionally seen, but are generally inaccurate. They have the advantage of being able to carry a long range explosive payload without the recoil and mass of a regular cannon.
