Synergy has transformed for its official launch, introducing new features that enhance gameplay, including new plants, seasons, and storylines. The game has evolved from a city builder with limited resources and storyline to a more complex experience influenced by solarpunk themes, where players care for refugees and establish sustainable settlements. The full release includes a dynamic temperature system that introduces challenges such as severe dry spells and the need for new tools. Players must also manage emerging threats like contagious diseases, necessitating the establishment of hospitals and scientific districts. Improvements in building systems include a unified water supply that simplifies resource management and enhanced monitoring tools for better strategic decision-making.
