Just finished Perseus Mandate yesterday and with that have now completed the whole package offered here. First of all, this is a great value you get here with the Platinum Edition. It will take you some time to get through the main game and the two addons. The game and the addons are pretty good but haven't aged that well IMO. Sure, the AI is impressive and the SlowMotion shootouts thrilling but the level design is everything but impressive and the game itself is pretty repetitive. So what I recommend is to set the difficulty at least on high so you get the most out of the shooting because there isn't much more to it really. The story is, although pretty simple, not very well told (worst combo IMO) and I lost interest very quickly. And yeah, the horror elements are there but are repeated over and over again, so it does get a bit tiresome - especially if you play the main game and the addons in a row like me. And that's about it. There isn't much more to tell. This is pretty much an OldSchool shooter. Better be aware of that before you jump into it. I have to say that I personally liked Perseus Mandate best of the 3 because it gives kinda of an outside perspective on the events of F.E.A.R and EP. Also I though it had the best shock moments and on top of that a challenging boss fight at the end (something totally absent in F.E.A.R. and EP). EP on the other hand felt and played like a chore. It didn't add much to the story and felt like the devs just added a few levels at the end.
