Updating script support, taking requests

[Your Computer]

Is it possible to create a flying enemy that can swoop the player from above, or an enemy that uses projectiles to attack from a distance?

EDIT: Is it also possible to have one enemy attack and kill another?

Except perhaps in some "hacky" and very unpleasant or unsatisfying ways (unless the HPL2 engine gets heavily exposed to scripts), an enemy that swoops down to attack the player may be the only thing remotely possible.
