Well, after finishing the game I must say that it is pretty boring. I was expecting a better story, some adventure elements in it... it's simply a shooter disguised with catchy main characters. The story of the game goes to the toilet after some time in it, really I was very disappointed towards the end of the game.
It's plagued with stupid level design, for example you solve a puzzle and unlock a secret passage. You enter the passage, and the torches are lit (wtf! I'm the first one to walk that corridor in about 300 years!!!). And the worst of all, there's always enemies, waves of them, in the most stupid places. To me towards the end this game is like doom III: nice graphics and technology, boring gameplay at the end. They sohuld have stressed more in the puzzles and adventure elements. It starts as a brilliant film, with solid characters (even if they are some cliché) and nice dialogs, with good premises and a nice setting. But all of that is thrown away later on. There are tons of inconsistencies in the story. The enemies you fight at the end and the final locations are simply ridiculous in its own context.
There's also that stupid sense of "difficulty arch" through the game, and they like to put that in games nowadays, that is quite irritating because it's only a cheap way to develop AI. So, at the beggining of the game, a headshot is an instant kill. At the end, you can almost empty a clip in the head of your enemies and maybe they are still alive (I play on hard, by the way).
To me, this game has next-gen technology and the same poor decisions as any hollywood movie for the masses regarding gameplay and script. Really, it feels a bit rushed, mainly because platform and puzzles can totally be ignored in this game and feel off.
Absolute linearity is a must in this game, I would have like maybe a different approach, and having the chance to explore maps on my own (after playing Crysis, the rest of games seem limited in comparison).
Graphics: 9
Story: Begins with a 9 and ends with a 5
Gameplay: 6-7
Sound: 9
Conclusion: big production value, the game goes down and down the more you advance. It evolves from an Indiana Jones adventure to a shooter unnecessarily.
