Vexx review. Classic Game Room presents a CGR Undertow review of Vexx for the Xbox developed and published by Acclaim. Vexx is a 3D platformer that tells the story of the planet Astara. Seven hundred years after its destruction, it still remains as habitable fragments. These fragments are where Vexx does his work, clawing and platforming as he avenges the murder of his grandfather. It's less interesting than it sounds, but Vexx does offer some quality platforming.
