This battle is very easy. When the battle between Eckhardt and Lara begins, a magical barrier will appear around the center of the room. You cannot touch it or you will lose 10% health. Eckhardt will keep running around the barrier, launching attacks. First, he will shoot two lighting attacks. Each attack does about 10% damage. To avoid these, duck down (get on your stomach to make sure they do not hit you). Next, he will jump up and teleport to another part of the room. When he reappears, he will launch two more lighting attacks. He will repeat this process one more time, then he will start to duplicate himself. He will do this three times. His copies will then run to the center of the room and launch their most powerful attack. It will cause you to lose 20% of your health. You will see little sparkles on the floor. Either get close to the barrier or stand in between two avoid the hits. After this attack, Eckhardt will fall in the middle to regain his strength. You have about five to seven seconds before he gets up. When he is down, run over to him and punch/kick him. A short intermission sequence featuring Lara stabbing him with one of the shards will appear. Repeat this process two more times to bring him down. Note: Eckhardt will switch between lighting and fire attacks. There is no difference between them.

In the battle with Eckhardt, do not use any weapons; only kick him.
