First of all, go up to the edit menu of this notepad and select WORD WRAP if a check isn't next to it already.

The prefab is in .map format.  Simply load it into worldcraft and you will see a collection of entities in black space (if you see white patches in your black space, then you need to upgrade to WC 2.1).  There is a letter in front of each collection of entities.  To put these in your prefab menu, select each group individualy (without the signs) click on the "create prefab" button and give it a name and put it in one of the existing prefab directories.  I suggest naming the prefabs monster_spawn_a through c.  

Now start your level and place the prefab.  Simply make something target "riftmanagera" and it will teleport a headcrab in just like in the picture.  You would of course target "riftmanagerb" and "riftmanagerc" for the other two.

There are probably a few things you would like to change.  First of all, create a fresh one from your prefab menu and ungroup it.  Now, you will notice a collection of 16 info_targets surrounding the middle.  These info_targets are in layers.  All four targets in the bottom layer have the same name.  The each of the other layers has a unique name also.  Each of the four beams targets one of the four riftstrike points.  This way the beam strikes are random.  However, you probably want to move each landmark onto a wall so that the beams will strike walls rather than stop in the middle of the air.  If you want one of the beams to hit a certain spot, just delete all but one of the strike points for one of the layers and put the remaining target where you want the beam to hit.

Finally, you probably dont want to go through all that trouble to spawn a measily head crab... so select the big purple block in the center (that is the monster maker) and change the monster to one that is more to your liking.  Just erase "monster_headcrab" and put the name of the new monster...ie "monster_alien_slave".

Now that its all good...you probably want to put a bunch of these in your level.  For your convienence I have made three spawns for you.  If you want more, you will have to go into one of the groups of objects, say spawn group "A" and change every letter "A" in the the "value" field of EVERY ENTITY IN THE SPAWN GROUP to a new letter "D".  If you have more than one spawn point "A" in your level then they will both fire at the same time...and the beams may strike the wrong spots..,

I recommend editing the things in smart edit mode...

The only other changes you might consider making if you are a more advanced designer, is selecting the four env_sprite entities and increasing their scale.  This will make the flash bigger, which you might want to do if you are spawning a big monster like the monster_alien_grunt.

Thats it.  The first three will pretty much work out the box, but you need to change all the letters in one of them to make more...  

Remember that worldcraft looks at a capital "A" and a lower case "a" as two different letters.  I just always use nothing but lowercase letters myself.

Oh yeah...if you use this in any released maps then don't forget to put me in your credits and tell'em what site you got the prefab from.
