Some people complain about classic Tomb Raider having controls that are too complex, but this is proof that the opposite is even worse. The platforming in Legend is practically automatic, there's no resource management and puzzles are absolutely trivial. As a result, this entry is much shorter than a classic Tomb Raider game and relies a lot more on gimmicks like those scripted vehicle sections and combat against sponges.
The atmosphere of the original is also gone because you are never alone, there are 2 omnipresent idiots always commenting on everything through Lara's radio. It's awful.
On the technical side, this game is buggy and it's impossible to play with the keyboard alone on PC because most of the gun related controls don't work.
