This is one of the best, most nostalgic Half Life flash games out there, because this time it's an ACTUAL GAME WITH DIFFERENT LEVELS. Other ones are just jokes, or broken flash demos. I personally like this one. But there are some issues. The camera angle system is way to slow, and on my system, accidentally pressing CTRL with W will close the tab, so I frantically have to watch my finger movements when crouching or else I'll mess up. But anyways, the rest of the game is actually... Quite decent.
