GameSpy reviews the latest addition to this 20-year-old series, and scores it a 4.5/5.
"WayForward pulled it off. More than that, the company completely nailed the look and feel of classic Contra. Taking inspiration from the first three games in the series (the SNES version in particular), Contra 4 feels like the 16-bit sequel that we never had. Everything from the graphics to the music to the animation to (most importantly) the gameplay will take you back to a time before Konami felt that it would be a smart idea to include cardboard 3D glasses with the latest Contra release."
