Hedgewars is the best free alternative to Worms: free, open-source, turn-based artillery with destructible terrain and both hotseat and online multiplayer, in continuous development since 2004 and about 180 MB to install.
Turn-based artillery with silly weapons and destructible terrain is a genre almost entirely defined by one paid series. The free option is a faithful, actively maintained take that has been going since 2004.

Hedgewars is turn-based artillery with destructible terrain, dozens of absurd weapons, hotseat and online multiplayer, and a 180 MB install. It is the direct free equivalent of Worms.
How it differs from Worms: Hedgehogs rather than worms, and a slightly different weapon balance. Presentation is charming but less polished than recent commercial Worms entries.

Hedgewars is just damn cute. It's immediately understandable, surprisingly deep, and just weird enough to stick in your head. It takes the artillery mayhem of Worms, replaces the soldiers with homicidal hedgehogs, and turns it into a polished free and open-source multiplayer game.
For the same living-room competitive energy in a different genre, SuperTuxKart handles local multiplayer chaos just as well.
The difference: Kart racing, not artillery. Real-time rather than turn-based.
SuperTuxKart is the kind of free game that's impossible not to recommend. It's instantly accessible, genuinely fun with friends, packed with tracks and modes, and backed by a surprisingly active community creating new content.
