"Spectral Force 3" features a number of gameplay similarities to existing game series, including "Suikoden" and "Fire Emblem". As in the more recent "Fire Emblem" titles, gameplay is essentially a series of tactical battles broken up by opportunities to improve equipment and converse with members of the team. Although there are missions which must be completed to advance the plot, the player is also free to pursue a number of mercenary contracts for any of the ten warring factions in the game. Doing so increases the level of friendship with that faction, while decreasing the level with any faction which was negatively impacted by the mission. While the player completes contracts, the war rages on around, with each faction trying to seize territory from rivals. After certain missions or game events, entire factions can wind up being eliminated from the map.
