Game show for children. Three Earthtwerps - or children from Wolverhampton - journey deep into space to take on CBBC's worst bad guy Ludus. They must play his interactive computer games to rescue their friends and family who have been turned into holograms. If they win, they can bring them home. If they lose, they will be trapped by Ludus in his game for ever! And in a first for the channel, viewers at home can play along with the same games at the same time by downloading the free Ludus app from the CBBC website. Show less
