Alien Arena — About this game
Alien Arena challenges Thor and Zespar to capture the opposing flag while protecting their own. Colour-coded pieces assemble offensive or defensive objects, one at a time. The status bar shows the remaining requirement; a finished object must be carried to its deployment position. Early in each round, the barrier leaves time to prepare before either player can reach the opposite side.
