POLYGON

It was important for me to reach the point where the project no longer looks like a rough prototype, but begins to show its true direction. And I feel that moment has finally come. This is the first entry in a new development diary series, where I’ll be talking in detail about the core mechanics of Polygon //. And today, we’re starting with destruction: Destruction in Polygon // is part of the gameplay. During combat, the environment gradually changes. Familiar cover disappears. Buildings lose their shape and reveal new sightlines. This makes every situation less predictable. You don’t just move through the map. You reshape it. I wanted the environment to stop being a static backdrop. Every instance of destruction is generated procedurally. There are no pre-recorded animations and no predefined patterns. The shape of a breach depends on the impact point, force, and conditions at the moment of the explosion. Because of this, each match unfolds differently. You can create new paths where none existed before. Or deny your opponent their usual route. Destruction becomes a tactical tool — one that directly influences the battlefield. In most shooters, moving objects and physics calculations are processed on the client side, meaning on your PC. The server mainly handles state synchronization between players to ensure proper interaction in multiplayer. However, with this approach there is always a risk of desynchronization: the server and the client may interpret the same event slightly differently. As a result, you can end up in a situation where, from the player’s perspective, the aim was perfect, but the hit was not registered on the server. In Polygon //, server-side physics became the foundation of the destruction system. To ensure determinism and absolute synchronization of destructibility, all critical logic was moved to the server. This guarantees that two different clients always receive an identical simulation result, regardless of their performance or local conditions. Existing off-the-shelf solutions did not meet the needs of Polygon //. Most of them are either too performance-heavy or, more importantly, not designed for proper network synchronization. A significant amount of work went into developing a custom solution focused on high performance and stable multiplayer behavior. As a reference for quality and scale, I relied on the approach implemented in The Finals, which represents one of the most advanced destruction systems in the modern gaming industry. I am sincerely grateful to the developers of The Finals for publishing their development diaries. The publicly available technical insights and breakdowns of their solutions significantly helped me in designing and refining the destruction system architecture for Polygon //. The following video showcases very early development footage of The Finals that is publicly available. Each detached fragment has its own physical properties. Debris does not disappear after impact and is not just visual dressing. It has mass, inertia, and continues interacting with the environment. Falling elements can damage other structures, trigger secondary collapses, and even injure players or damage vehicles. Destruction doesn’t end with the explosion — it can cascade. Almost every building on the map (except for those critical to gameplay balance) can be destroyed down to its foundation. There are no permanent safe structures. If a building stands, it can be weakened. If it can be weakened, it can collapse. Over time, a prolonged fight can quite literally reshape large portions of the map. The blast wave does not stop at the point of detonation. It propagates through connected fragments and structural elements. If a building is held up by only a few remaining supports, even minor additional force can trigger a chain reaction. A small explosion — or even the impact of a heavy falling fragment — can result in a full collapse. So taking cover in a heavily damaged building might not be the safest decision :) Vehicles will also play an important role in Polygon //. And of course, they can interact with destruction as well. Mass, momentum, impact — all of it matters. But I’ll go into more detail about vehicles in a future dev diary :) Destruction is one of the key steps in the direction Polygon // is moving toward. It’s not just a visual feature or a one-time experiment. It’s a foundation for scale, dynamism, and unpredictability in combat. Work on this direction is ongoing, and there is still a lot to improve and refine. In the upcoming dev diaries, I’ll cover other aspects of Polygon // — technical solutions, gameplay mechanics, and how the new installment is taking shape step by step. Developing a game of this scale is a long and costly process. Polygon // is being built almost entirely solo, and every new mechanic requires time, resources, and an enormous amount of work.
