Serpent — About this game
Serpent turns a futuristic sport into a contest of moving walls. Steer your growing machine to surround the rival or trap its head, while avoiding a route that leaves you sealed in. Missiles alter the opponent’s speed and length items reshape the arena, but the unusual relative-turn controls matter first: left is a turn from the machine’s own point of view.
Select one player and the first difficulty, then start with START. Practise pad-left for a relative left turn and A for a right turn while moving in different directions before attempting to enclose the rival.
