Dear Survivors,
[/p][p]With City Defense Z, we are entering a brand-new era in this tough but thrilling journey we’ve embarked on together. Today, we’ll share with you the major innovations and systemic transformations coming to City Defense Z in the upcoming period. Which mechanics are evolving, which systems are being introduced for the first time, and what maps await you... All are covered in this roadmap.
[/p][p]
But first, let’s take a brief look back.In the past few months, we launched the demo and had the chance to test the core gameplay thanks to your valuable feedback. Then we made an important decision: we took down the demo. The reason? The updates we made began to fundamentally change the core dynamics of the game. The demo, in its current form, no longer represented this new structure, and we didn’t want it to create a misleading first impression.
[/p][p]During this process, we re-evaluated the core design of City Defense Z, and the game has now evolved into a
rogue-lite structure. With permanent progression systems, a replayability-focused design, and ever-changing strategic decisions every run, we aim to deliver a deeper and longer-lasting experience. Now it’s time to explore where this world will evolve together.[/p][p][/p][h2]
