Your hand is held throughout the game. You press buttons when told to, and six hours later you get the end credits.
The entire game is an exercise in "When you see the yellow mark/blue circle, click the mouse/press the spacebar". There is no challenge, no real puzzle solving and no independent thought in the gameplay. Even combat is easy, with the hordes of identically-dressed generic mercenary bad guys being such bad shots they manage to miss Lara completely while she perforates them with bullets.
It's worth a look if you're a fan of the series, as an insight into the character of Lara Croft. You also get to see and explore her Manor and see parts of her past. However, don't bother if hand-holding annoys you.
