Adellos is a turn based fast paced tactical strategy board game for 2-4 players. Each player controls a medieval fantasy noble, who hires various units and tries to overcome the other players. Everyone plays a different faction (Royal Army, Clergy, Rebels & Undead) and the players have different units with unique skills to choose and control. They also have to manage their gold income and the flow of action cards that can be used on their and enemies turns for effects that influence the game. Everything takes place on a symmetric battle map and every noble has a specific skill that influences the game from the start. The game can be won through K.O. or „King of the Hill“.
Turns are played in two phases. During the first phase, players gain resources their units provide. In the second phase, players hire units, move, attack, or play action cards. Every action costs a specific number of action points. The players start with three action points and a fix amount of gold. Players can increase their action points throughout the game to build up huge turns.
