Overview

Nextbots: Sandbox is a 3D sandbox action game focused on survival in a dynamically escalating environment where the player is constantly pursued by AI agents (nextbots).

The gameplay loop is simple but highly repeatable: survive → take risks → gain rewards → progress. The main focus is pacing, player reaction, and using the environment as a survival tool.

The project was developed as an independent product with a strong focus on rapid gameplay iteration and hypothesis validation through live metrics.
