I have this game on my phone and love it. However I'm stuck on "Speed Demons" Where Sideswipe, Sunstreaker, Prowl and Smokescreen go up against Megatron and Trypticon. I can never seem to defeat Trypticon before he spews out Soundwave and a bunch of Seekers ending the game. Has anyone defeated Speed Demons and how did you do it? Many thanks.
