It's not accurate to call this a difficulty curve, because it applies over multiple plays of the same level. The difficulty in the game is just engineered brilliantly. Other notoriously hard games, like scrolling shooters, stay hard forever; you can practice until you complete the levels, but it is a boot-camp-like experience that requires serious dedication. With Contra 4, my performance improved noticeably with every session. It is both unrelentingly difficult and instantly gratifying. I can think of no other game that achieves this kind of personal progression.

I can't believe that the same WayForward that was responsible for Ping Pals and a string of licensed GBA games has somehow done this. It's not an American interpretation of Contra. It's not a Contra tribute game. This is, in fact, a real Contra game. It feels very Japanese in execution, focused more on enemy placement and carefully-orchestrated levels than on loading the player with abilities. In fact-- and this may sound crazy or blasphemous-- I think Contra 4 feels like a Treasure game.
Like Alien Soldier, the controls feel a bit overcomplicated at first (especially the R button, used to anchor your character in place to allow for easy 8-way aiming), but once you have learned how to use them, you realize how flexible your movements become. From the very start, the game trains you to use the new grappling hook mechanic as a dodge maneuver rather than just a conduit to the other screen. Also like Treasure's games, the game throws hilariously overblown level designs (like a level that takes place on a missile in flight) and screen-filling bosses at you. Much like Treasure's classic action games, Contra 4's weapon system, in which you can swap between two weapons, or power one up by carrying two of the same kind, allows for highly customizable gameplay. Unlike former Contras, you now have the opportunity to carry a weapon even after you've died, allowing you to choose the weapon that is most appropriate for each area.

Once you manage to complete the game, even in the abbreviated but still painful Easy mode, you unlock Challenge Mode. Challenge Mode is a series of bite-size levels that task you with completing an objective: beating a boss or a rush of enemies in some of the more conventional challenges, completing a stage with a certain gun or no gun at all in the more unorthodox challenges. As you would expect, these are brutal, but they also provide the only real short-session play available in Contra 4. They also provide the means of unlocking a bunch of series-tribute items, including playable characters from past Contra games, comics, artwork, and even decently-emulated NES versions of Contra and Super C.

Like every other aspect of the game, the presentation is something special. Everything about it is classic Contra, both paying tribute to and building upon the brilliant style exemplified in previous games. The graphics are exactly what a 32-bit Contra sequel should be: vibrant, colorful, intricate, and beautifully animated. virt's new soundtrack brilliantly integrates elements of Contra's signature tunes into new rockin' compositions, which are matched to visual cues in the game in ways that will probably force an emotional response. For instance, you emerge from a cave to find ... a rushing waterfall, just as the familiar strains of the Level 3 music from Contra begin to kick in. More than nostalgia for the old games, it creates a pervasively Contra feeling, and reminds you that no other series has done as perfect a job of conveying the feel of a level through its music.
My appreciation of Contra 4 is not nostalgia. It's not a great shooter simply because I love the first game. Nor is it great for 2007. That it happened to come out in 2007 instead of 1992 is no matter; it would still be brilliant in any time period. With the expertly-designed level progression, the top-notch visuals and audio, and most importantly, the note-perfect difficulty, WayForward has proven themselves to be a developer worthy of attention. As controversial as it sounds, Contra 4 may be the best Contra game yet. It's certainly one of the best run-and-gun games ever made.

Final verdict: 10/10
