string TextPlayerKilled string TextPlayerExecuted: Info text displayed in the bar at the bottom of the screen when a player was killed (by another player or during an execution sequence, respectively) and is watching his or her ragdoll.

simulated RegisterOverlay(Actor ActorOverlay): Registers an actor whose RenderOverlays function is called each frame. Must be called client-side to be effective. Note that actors of any class can be registered, not just JBAddon actors.
simulated UnregisterOverlay(Actor ActorOverlay): Removes an actor from the list of registered overlay actors. It is generally safe to simply destroy a registered actor, but it's cleaner and beneficial to performance to unregister it before.

The JBAddon class provides a bIsOverlay property that can be set to automatize the use of this. See Jailbreak Add-Ons for details.
