I mean... in those tutorial videos, Joe explains ALL that come with that particular module, and the thing you can do with it.
He also explained how you can code some of them.
There is no "native" monster shoots script... it means you will have to code it (like the player shoots projectile... just make another one, change some constants to use a different projectile object and assign that script to a AI action.. like Joe explains for the monster movements for example).
You could say that: if not in the tutorial videos means not in that version.
Reminder: this version, with its module is for the SUMMER CAMP, for us to experiment.. customize, ... trying things. Of course, the module is missing a lot of scripts... those scripts will be in the definitive 4.5 version.
