Coming from childhood here, you cannot simply skip on Contra when it comes to NES classics! It's the best run and gun on this console you can play. Challenging alone, but easier and more chaotic when played with a friend.

The military and secret alien base thematic really brings out the 80's trends. I recommend to grab that "S" power up and blast the whole screen away with multiple bullets, it's just so satisfying and fun to play with!
