Kickass game.
Made me sad we never got a sequel or a (decent) 3D worms game.
I'm told the PC version is complete garbage. Allegedly they couldn't fix the AI so to compensate made the enemies stand still but have pitch perfect aim. That's pathetic if true but I never played it on PC.
The PS1 version is excellent and I highly reccomend anyone who has a PS1 or PS2 kicking about to give it a go.
But good lord beating the Campaign the 2nd time around (Hard Mode) is a nightmare. Especially if you leave no Pig behind like I do. You have to exploit the crap out of the bad AI
