I totally played Earth’s Special Forces back in the day, but I completely forgot about this modification for the original Half-life until I read a blog post on Kotaku. Basically, Earth’s Special Forces is a third-person fighting game based on a little anime series called Dragon Ball Z. As you can see on the trailer embedded on top, the mod allows you to select your favorite character, fly, transform, use special attacks and so on and so forth.
The latest version of Earth’s Special Forces is very different from the one I played: visuals have been improved significantly, bugs have been fixed and player models have been updated. Fans of the Japanese anime should get ESF right away by following the link below.
