Kismet questions, 2D sidescroller

[arucart]

Basically i'm making two games. Is there a way to make a RB_RadialForceActor push the player back or would i need to use something else.

Also i'm trying to add a sort of boss life system that when he is hit three times he'll end up dying.

Lat question I can set up the camera to 2D through kismet but when it comes to setting up the cross hair i'm having major difficulty.

Well for the boss question.

Use attach to event, attach the boss spawn to take damage event.
On the take damage event out have it increase an Int value and check if Int value is > 3 if so Destroy actor.

For the other two ill have to defer to others.
