It was my first time playing Code Veronica, and I really enjoyed it. The story was pretty neat, and the puzzles were just hard enough, I didn't need to look up a walkthrough for them. All of the achievements except for a couple are story related. The two weapon achievements I think are really hard, and I personally will most likely not unlock them anytime soon. It's an easy 700/1000, just those two weapon unlock achievements are a real pain, unless you're a veteran to the series. If you liked the third game, you'll probably enjoy this one as well.
