Thundercade / Twin Formation — About this game
Thundercade sends a motorcycle through military resistance with a gun and air support. Collecting parked sidecars changes the weapon coverage, letting the bike handle threats outside its original forward firing line. The ground route still contains obstacles to steer around, so extra firepower does not remove the need for a clear escape. A stocked bomb calls an air raid when ordinary shooting cannot open enough space, making its timing another part of surviving the advance.
