Game show for children. Three Earthtwerps (or kids from Swindon) 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. Win, and they can bring them home. Lose, and they will be trapped by Ludus in his game for ever! And in a first for the channel, viewers at home can play along the same games at the same time, by downloading the free Ludus app from the CBBC website. Show less
