Start a spectated arena fight in a settlement.
- To start an arena fight, the player must build the blue and red arena pads near one another and then assign creatures or settlers to them with the workshop interface.
- Prior to beginning the fight, the player must build and activate the quitting time siren in order for the fight to be considered spectated, otherwise the achievement will not be unlocked. For best results it should be built near the arena pads.
- After assigning contestants to each arena pad, they will be immediately hostile towards one another and attack on sight. To work around this, assign only one person to either pad, then build walls around them to obstruct their view of the other pad. Activate the quitting time siren to draw the settlers near, then assign one to the opposite color pad and remove the walls.
