Worms: Source is a source modification of Worms: Armageddon with more weapons, levels and innovation.
It’s based on a map built out of “puzzle peaces” – Brushes that fit into each other so it looks like the map deforms once they blow up. They are all func_breakables.
The mod allows 4v4, 3v3, 2v2 and 1v1 matches with the standard side-view camera.

This allows for some totally crazy online matches with some totally kickass weapons. The person in control of the worm in focus has 30 seconds to get in position and fire his weapons. Players get kicked fro being AFK.

The gamemodes in this mod is Campaign, Co-op, Skirmish and Puzzle – all online.

I just thought of this yesterday. It would be so awesome to play worms with decent physics and effects:D
Count me in as a mapper.

I think this gamemode idea is great! Count me in too to help test if you make it and need some testers.

Bad thing is, It's already been done. :/ But the good news is, it's in wire, and not a sourcemod.
