There are some doors in round 5 which you can go into.To go in,Pick up a person(works well with Haggar because he's the only one who can move while lifting)and throw him towards the door.If it is a white dead end room,go out.If it is a blue room with a small opening,go in(you will have to fight Dirk and Ray first.) You will arrive at a computer room. Break all computers and you will not have to fight Stray.
When you start round 3 you will see two windows and a pipe. Go to the far right window. Pick up a enemy and throw him twords the windows and the pipe. After you have broke the windows and dented the pipe you will go on. Break all the other windows and you will not have to defeat Caine.
