“You are the Corporal Daniel Shephard, after crash landing on your way to Black Mesa, your brother Adrian became a Corporal in less than 3 years, very few people have ever become a officer that quickly. As a lowly grunt you have been given the perfect oppurtunity to prove yourself and show that Adrian isn't the only successful one in the family. Escape an infested research facility with aliens and a whole battalion of Black Ops... its going to be hell." This was originally created by B-dama (see his readme for contact details)
A new hero, created in Black Mesa labs (don't ask me why - not only is this information classified, but I also have literally no idea).
A skin for Half-Life Opposing Force. Gordrian Freephard, a new bio-engineered hero, created by crazy Black Mesa Scientists. Basically a combination of DNA samples of Gordon Freeman, Adrian Shephard and Race-X aliens. Don't ever mention his ridiculous tie, if you want to survive!
