Captain America is one of great game in NES era
You must go through places in America's map. Every place, there are some enemies, diamonds,....You must beat these places to next target.
You can collect 100 diamonds to upgrade your skill (return shield and explosion bow). When both 2 characters are in a place, they will go together.
In 2 players mode, player 1 control one in 2 heroes, and player 2 control 1 in 3 boss. But this part is boring because 2 of 3 enemies can fly, so if you choose Captain , you can't do anything. Totally, 2 players mode is so bad.
Music is good but repeat
You must cost one hour to complete the game. There's nothing more to research but totally Captain America is a good game in 8-bit era
