Crisis Force

One of the best flying games on the NES, released by Konami in 1991. The gameplay is exciting: collect prizes, improve your weapons and armour. And for a certain amount of prizes, your plane transforms for a while into a huge and fearless ship that has no obstacles. The most interesting idea of the authors is the transformation. By pressing A, you can choose one of three types of plane. Each type has its own super weapon (press B and then A) and fire advantage: the first type is capable of destroying everything in front of you (especially if you have a lot of weapon bonuses), the second type not only shoots forwards but also protects you from behind, and the third type shoots sideways and forwards. At the end of each level there is a very big BOSS waiting for you. As for the graphics and sound, there can be no doubt - everything is top notch.
