An old old game. It is indeed similar to Worms, the key difference being that it is played in 'real time', i.e. it isn't turn based. It's played split screen on a single computer. The keys are quite bizarre, but pressing 'change weapons' and 'jump' at the same time to fire a grappling hook becomes second nature to you, after a while. The modern game it's most similar to is Soldat. You *can* play against the computer as opposed to a mate, but the AI is terrible (and suicidal). In my opinion, Liero is best played with player health set to 30%, as this makes the Gauss gun, Rifle and dreaded Zim all one shot kill weapons. Have fun.
