MP era with six new factions, mostly new units. Fully playable with new abilities, traits and specials all working. Feedback welcome, see the forum thread under Faction and Era Development.
Updated from Wesnoth 1.14 to 1.16 by Atreides. Seems to work just fine, let me know if there are any problems. All units now have at least generic attack sounds.
Can be combined with the Lonely Era now! Both must be installed of course. Together with the default it comes to 20 factions to play with or against.
