fun through and through!

So far, quite enjoyable. wish I could shoot the zombie right after you get knocked out. It would put the soldier out of his un-ending torment. At least if it is like the zombies in halflife 2.

I wouldn't go out and say this is the version of Half-Life you should start on, I actually feel that starting with the original would be best. Coming back after playing Half Life 1 makes the experience all the worth more playing.

Love the game reminds me of the Oblivion remaster in terms of how it came about
