To describe this space battle as frantically fast and furious is an understatement. I have been through all eight waves of Arcadia (a noted toughie) but I could hardly dent this one.
There is a technique... bob up and down to clear a path. Anyway, the old faithful spacecraft has been unleashed against a host of megarrific aliens who are cemeted together by their loyalty to a Dodo. There are nine waves to survive: you are static while the horrendous hordes scroll your way, lobbing the odd star shell or something similar.
The purple meanie missiles must not be allowed to reach your side of the screen while the more you blast at the Buildas, the quicker they multiply. Smash through using a shield, unless you can shoot faster than they can breed.
This has good battle sounds, bright colours and is well worth the frustration it causes.
