Fantasy Wars is a turn-based hexagonal wargame set in a fantasy world. After many centuries of peace, the human Empire of Eolia is at war. Influential lords have founded their own kingdoms and try to occupy as many territory as possible. The internal struggle weakens the human race and makes it vulnerable for attacks from orcs and goblins from the south. Outnumbered, the humans ally with the elves and dwarfs to withstand the invasion.
There are three campaigns to choose from: Humans, Orcs and Alliance, and the third only becomes available after finishing the first two. While playing, the 3D environment is covered with a grid of hexagonal cells. Only one unit can occupy a single hex. Armies consists of various fantasy creatures that can be deployed. Typically the player need to complete quests that involve occupying new towns or taking out other armies. More than 500 units can enter the battlefield simultaneously. Various camera positions provide panoramic overviews as well as close-ups from the battles.
Each unit has detailed characteristics based on experience, hit points, artifacts, protection, movement, speed, range of sight, attacks and special abilities. In a single turn, players can move units around, command them to attack or deploy new units from the reserve list. When attacking, a battle forecast is shown, predicting the losses for both sides. Players can improve their chances by tactically positioning the units on higher ground or according to their abilities for melee, ranged, covered, magic or flying attacks.
New units can be bought during the missions and taking them through many battles provides level ups and new perks, up to five levels. Armies also come with very strong units known as heroes. They can level up ten times. The death of the hero commander usually means the mission is failed.
To get an overview of the entire battlefield, there is a 2D strategic map. Both offline hot seat and online multiplayer games are supported.
