Even though I've played through this game for PC, I'd always wanted to try out this verison of it too. I'm pleased to see that there are a fair amount of new things in this version to keep me (and probably only me) interested. For one thing, it's using the models and sound effects from the enhanced visuals pack released with the PC version of Half-Life: Blue Shift, but it also has new models and animations for all the stuff hanging on the walls, like the health stations and eye scanners. There's also a new intro to the Hazard Course section that I didn't expect (complete with more lines for the scientist characters) and re-recorded lines for much of the hazard course for anything involving a reference to a "key" changed to a "button". There's also a new section in there talking about how to use the lock-on feature which is probably the most perfect lock-on I've ever seen in a game. You have to point pretty close to them to do it, but once you do you only need to manage the verticality of your view. A bunch of small things, I know, but I enjoy discovering them all the same.
