Dino Rex (US) — About this game
Dino Rex (US) makes its dinosaur duel depend on different head and lower-body attacks. Directional input changes the strike, while Down followed by Up produces the unusual neutral jump. Roaring builds the side meter into stored POWER icons, giving a reason to find space outside the immediate exchange. Six selectable dinosaurs bring different reach and attacks to the tournament, whose winner must take two bouts in a match.
