Timesplitters Future Perfect - Cool trick on Mansion Of Madness Co-op

This only works in Co-op mode.

When you get to the room where crow pulls the lever and causes Cortez to fall into the mine cart, get the second player to walk in front of the cart until you get to the area where the track splits into two different directions, the second player should then stand on the left side of the track. Now the mine cart should hit that player causing them to move as fast as it does.

If you can manage to stay in front of the cart until the video starts it will show the second player in front of the cart for a second and then they will disappear.
