I don't get it. Why does this exist? How did Gordon Freeman end up on the island? Also btw I trapped myself at the part where you destroy the helicopter because I think I shot an RPG at the helicopter earlier. Yeah so basically I had no idea what to do the whole 10 minuets of gameplay. Lol I'm not sure if this was free because I got it in a bundle with other valve games. It probably is free.
