Cute chic, good single opponent AI. Although you'll still get stuck on door jabs etc as in half Life 2.
Also whats with the monster in the construction grounds? Some explanation would be nice.
If you loved the Half Life 2 engine, get this game. If you like going against human opponents, this one works as well. Looking forward to part 2. Hopefully by going episodic they come more frequently.
Nice writing as well: not exceptionally inventive, but lots of fun and doesn't seem to take itself too seriously.
