A rocket is a very complex apparatus, consisting of many parts and assemblies. Especially difficult to deal with an unmanned spacecraft. If it fails, it will not help you. Our virtual scientists created a rocket controlled by just one red button. On the keyboard, this is the down button. Click on it when you need to bypass the counter obstacles and pick up ammunition. The rocket will be able to shoot, clearing the way.
