How do I make vertical rain

A while back I did the Ghost-Hunter game tutorial, and now I want to add a raining/stormy environment.

I've seen tutorials done for platformer-type games, but I still don't know how to make rain fall when the game is birdseye view oriented.

Any tips?

There's actually a version of the Ghost Shooter demo included with Construct that has that exact feature. You can find it on the list that pops up when you create a new project. It looks fairly complicated but if you break down the events one bit at a time you should figure it out.

Thanks!
