Siege of the Citadel: 3D Wall & Hallway Connector Pack

The 3D Wall & Hallway Connector Pack for Siege of the Citadel adds two three‑dimensional walls and a set of hallway tiles that snap together like LEGO, expanding the base game's modular board. The walls provide visual depth and can act as defensive barriers, while the hallway pieces let you link rooms and corridors in countless configurations, boosting replayability and the feeling of defending a real fortress. The expansion preserves all core mechanics—cooperative play, dice rolling, modular board, and variable player powers—so the rules stay untouched; only the scenery gets a serious upgrade. Components are high‑quality, with sturdy 3D wall miniatures and nicely detailed hallway tiles. This is perfect for fans of Siege of the Citadel who want a more immersive battlefield, or for lovers of cooperative games that love a good board layout. It doesn't affect playtime or player count, keeping the learning curve identical. In short, it's an aesthetic add‑on that adds layout options and a dash of drama to the fight against the Mutant Chronicles threat.
