Patch 2.0.0 will add spearmen for each playable civilization, while at the same time adding swordsmen for the Goblins. Spearmen serve as a counter to cavalry (they have a bonus against mounted units), but their cheapness also makes them easier to mass than swordsmen and axefighters. Spearmen will be trainable at the barracks, without needing to be acquired via tech points.
Another addition that the patch will bring is faction-specific languages (for name generation), available for certain factions. For example: when playing a Teuton tribe, the names of their soldiers will be generated in older languages (i.e. Old Frankish for the Frank Tribe), instead of being generated in German, thus providing greater immersion. For this end, careful research on those languages has been done.
