There is an old PC game i used to play, i believe it was on a 100 games in 1 disc or one of those type.
But it was 2D, you got a planet, and there was enemy planets, i think you could choose the size and health of them all.
in it you got to shoot missiles and whatnot at the other planets which took chunks out in the same way you do in Worms, and the aim was to clear the screen of all of them while they tried to destroy you too.
The only smaller detail i can remember is the enemy would often say in text "resistance is futile"
