Bus Fortress – Vehicle & Upgrade System Concept

A vehicle concept built around upgrade progression and gameplay clarity, designed with a zombie survival setting in mind.

I wanted this to feel like something that evolves over time, so the focus was on building a system rather than a single asset, how armor, weapons, and attachments layer onto the base vehicle while staying readable.

A lot of the work went into keeping the silhouette clean while still pushing detail, especially around the front plow, turrets, and modular attachments. The goal was to make each upgrade feel meaningful at a glance.

This was also a quick exercise in adapting to a specific game style and designing with implementation in mind.
