I am not searching for any game of the Worms series. So, a decade or so ago, I had this game on my old pc. In the game you were controlling like a worm or something, the graphics were pretty pixely I believe, everything was 2D, it didn't look very fancy. You battled other worms online or against cpu in a cave-like environment (I think it was meant to be underground in brown earth), which was destructible if I remember right. You had a bunch of weapons to use too, mostly projectiles I think. i think it had cheap pixel blood too.the game was free, probably maybe required dos. it certainly had the graphics of an old dos game i think it had L, R and B in the name, but I'm not sure. Does this ring a bell for anyone?
