Khoikhoi - Samuel Maharero
The Last Trek: Civilian units can cross other civilizations territory without the need for open borders and can use roads while in enemy territory regardless of era.
UU: Pastoralist: Replaces Worker. May obtain a beast of burden in a Cattle tile, allowing it to have double movement and making him finish improvements slightly faster.
UU: Ox Rider: Replaces Cavalry. Doesn't require horses, but requires at least 1 improved pasture in city. Has -1 movement and is slightly weaker, but performs a ranged attack before engaging in melee.
