To collect stickmen, you need to successfully complete various parkour challenges within the game. Each time you rescue a stickman, they will join your group.

In Human Vehicle Run, you start by building simple cars and gradually progress to more complex and powerful vehicles like trucks and eventually helicopters as you gather more stickmen.

There is no specific limit to the number of stickmen you can collect. The more challenges you overcome, the larger your team can grow, allowing you to create even more powerful vehicles.

As you progress through Human Vehicle Run, the parkour challenges become more complex and difficult, requiring better timing and skill to complete. This increases the challenge and excitement as you continue to play.

While the core gameplay focuses on collecting stickmen and building powerful vehicles, there are limited customization options available for the appearance of your vehicles. However, the focus is more on the size and power of the vehicle rather than its looks.

Currently, Human Vehicle Run is designed as a single-player experience. There are no multiplayer modes available in the game at this time.

Human Vehicle Run is available on multiple platforms including mobile devices such as Android and iOS, as well as on PC. Check the official store for the most up-to-date information.

The ultimate goal of Human Vehicle Run is to continuously collect stickmen and build increasingly powerful vehicles. While there is no definitive end to the game, the challenge is to see how far you can go and how strong your final vehicle can be.
