How do I make destructible landscape, � la Worms ?

Greetings!

I'm not working on any project that could use this, but I love the Worms (Worms 1, I'm old school) concept.

So, I just wonder about the possibility of a destructible landscape (like, making holes in it)

Is it possible? With a "maths" generated landscape, or with a background image?

I don't know anything about this subject, so feel free to inform me !

Well, in the Future I would love to create a Worms 1/Gunbound (Thor's Hammer version) mix, they have both an incredible and amazing gameplay with a perfect learning curve. Plus, they are absolutely fun.

First result for a search for worms:

It uses a math generated landscape, but a background image is also doable.

Ohhh, I whould have done this simple search, my bad.

Many thanks, dear sir.
