Ultimatum features different factions that you may play as. Factions are all different, and are balanced in many ways. Some factions have their strong and weak points, however a battle between two different factions would still be pretty fair. Here is a list of the current factions and a brief description about each.

The Humans are a balanced faction that focuses on everything. Human units are generally lawful or neutral due to their nature. The faction has a balance of melee and ranged fighters, with a couple healing units. The units are priced at around 16 to 20 gold for level 1 units.

Elves in general are great forest-fighters and most of the elvish faction can move through forests very quickly. All of the elvish fighting units (other than the specialty and spellcaster units) can use bows. Elves are also generally weaker in physical combat, but their melee combat makes up for it.

The undead faction is a large faction with inexpensive units. The Undead spellcasters are very powerful, and focus on dark magic. Some undead units can also convert enemy units into their allies as undead zombies. As a large group, the units are generally weaker than the other factions. However, the inexpensive units and the raising of the dead make up for the weaker units.
