YORG.io is a game with an original twist on supply chains and zombies. Your goal is to build a base which survives the night which is when zombies attack. Build and upgrade defensive towers to protect your base and try to survive as long as possible.
The game divides each playthrough into day and night cycles. During the day, players prepare their defenses, while at night they fend off increasingly difficult waves of zombie attacks.
Managing the flow of resources is crucial to survival. Players must construct crystal mines, factories, and a network of transporters to gather and deliver resources like iron, wood, and ammunition to their defensive structures. Optimizing these supply lines is essential, as the game challenges players to carefully plan the placement and upgrades of their infrastructure.
The tower defense aspect of the game is equally engaging. Players can build and upgrade various defensive towers, including arrow towers, cannon towers, and lightning towers, each with unique strengths and weaknesses. Strategically positioning and upgrading these towers to counter the escalating zombie threats is a core gameplay loop.
As the game progresses, the zombie waves become more formidable, introducing new enemy types and abilities. Players must adapt their defenses accordingly, upgrading both their towers and their resource infrastructure to keep up with the escalating challenges. The game's skill tree system allows players to unlock new technologies and improvements over time.
A key strength of the game is its high replayability. Each playthrough starts with a new configuration of available resources, requiring players to rethink their strategy and base layout. Additionally, the endless nature of the game encourages players to continually challenge themselves to reach new high scores and survive for as long as possible.
Players often praise the game's unique blend of tower defense and supply chain management, calling it a refreshing take on the genre. The simplistic but functional visual style and the satisfying loop of building, defending, and upgrading are frequently cited as strengths. While some technical issues, such as performance problems in the late game, have been reported, the overall gameplay experience is widely viewed as engaging and highly replayable.
