Songs of Syx, the cult-favorite dark fantasy city builder, just revealed its first major story expansion: The Sacrifice of Bob. Launching December 18, 2025, the DLC introduces narrative campaigns following eccentric citizens through vampire plagues, class wars, and ritual sacrifices in procedurally-generated metropolises. The trailer showcases the game’s signature deadpan humor amid crumbling districts and undead uprisings.
LabRat Games delivers structured storytelling to the sandbox builder praised for emergent narratives. Players manage multi-species cities balancing humans, elves, dwarves, orcs, vampires, and lizardfolk through happiness, hygiene, crime, and religious fervor. The Sacrifice of Bob weaves scripted events into core systems, turning random citizen deaths into epic sagas.
The Sacrifice of Bob Campaign
Bob starts as lowly sewer ratcatcher whose mysterious death sparks chain reactions across the city. Players investigate through district management – was it vampire feeding, noble conspiracy, or religious zealotry? Five interconnected campaigns span Bob’s rise (or undeath) from rags to potential god-king, each demanding different species balances and policy decisions.
New mechanics deepen vampire citizenship. Blood tithes fund district security but risk nocturnal uprisings. Daywalker policies force undead productivity at sunlight damage cost. Religious mechanics expand with sacrifice altars boosting fervor but angering humanitarian factions. Bob’s tale culminates in city-wide referendum determining his eternal fate.
Citizen Drama Systems
Songs of Syx tracks 100,000+ citizens with individual needs, jobs, relationships, and grudges. The expansion amplifies emergent stories through scripted hooks. Bob’s sacrifice triggers happiness crises, vampire migrations, and noble investigations. Players balance short-term stability against long-term faction approval.

Deepened Management Layers
Core systems receive vampire-focused expansions. Night economy thrives on blood imports while day trade suffers undead productivity. Religious districts generate fervor converting citizens but risk zealot riots. Noble houses scheme through Bob’s saga, demanding tribute or sparking civil wars.
Procedural maps generate alongside story beats. Mountain kingdoms favor dwarven forges, swamp cities breed lizardfolk shamans, coastal realms attract elven traders. Victory conditions vary – economic dominance, total conversion, ritual completion – matching narrative arcs.
| Species | New Mechanics |
|---|---|
| Vampires | Blood tithes, daywalker policies |
| Humans | Religious fervor, zealot management |
| Elves | Noble house intrigue |
| Orcs | Raiding economy boosts |
