Easy Compared to 1 and 2
First of all the Graphics are basically the same with some subtle things that make it a little better. Things like more image maps, clips that fall out of the gun when you fire. The water looks better. The sound is a lot better too. It lost that can like sound it had before. It's much deeper.
For gameplay, Lara controls just like she did in the previous installment. Crawling and swinging have been added this time though.
The levels are a lot shorter and dare I say, a lot easier than the first two. Some spaces are still a little tricky, but all-in-all, it's much easier now to complete the game.
It's an okay game. Bit of a let down compared to the other two. But I'm hoping it will get better as we go along.
