Gears of War: Stalactite Mechanic

I used Kismet to create a new mechanic for one of my Gears of War levels.  Shooting stalactites causes them to fall from the ceiling.  These stalactites insta-gib enemies, and provide cover after impacting into the ground.

Although it turned out to be quite difficult to drop a stalactite on a moving target, the cover provided by fallen stalactites helped turn the tables against the Locust forces.

A block of Kismet controls each stalactite.

The sequence begins when the stalactite takes damage from the player's weapons.  Once it has taken enough damage, a dynamic trigger volume attached to the stalactite is toggled on.  Any pawn that comes into contact with this volume is instagibbed.  The volume is turned off when the stalactite has impacted into the ground, so pawns are no longer hurt by them.  Once the stalactite has impacted into the ground, it toggles on a collision volume and associated cover nodes. Both players and enemies are able to use these as cover.

This dynamic trigger volume is attached to the stalactite, and kills any creature that touches it as it is falling.

This blocking volume is toggled on after the stalactite falls.

These cover nodes are toggled on after the stalactite falls.  In order to get them to build properly, you must uncheck bAutoAdjust and check bLooped in the CoverLink Properties.
