Contra 4 review at Gamespy.

"There was a time when videogames were the domain of men. Well, okay, boys -- but manly boys. And these manly boys played manly games. Games where dudes that looked like Arnold Schwarzenegger and Sylvester Stallone ran around and shot everything in sight: aliens, robots, army dudes -- everything. There weren't any sniper rifles or cover locations or rocket jumps or any of those modern-day distractions; just hordes of bad guys that needed their bellies filled with lead (or lasers if they were available)."
