Spider-Man 3 follows the plot of the movie while also tying in a few other villains to pad things out. Gameplay is mission-based and uses a system that is similar to
Castlevania II: Simon's Quest. Missions show up as glowing icons on a stylized map of New York City, which pulls double-duty as a play area and hub. Each section of the city is a short, self-contained, side-scrolling level that is connected to the other areas. While in these areas, you can either seek out story-driven missions or patrol that section for random crimes.
For the most part, Spider-Man 3 is a straightforward beat 'em up. It doesn't delve too far into Spidey's powers, but you have the important ones like clinging to walls, shooting webs and enhanced strength.
Again, story-based missions follow the movie's plot, which involves the New Green Goblin and Sandman stirring up trouble for Spider-Man. This leads to Spider-Man discovering the black symbiote suit (or should I say, the suit discovering him), ultimately leading to a showdown with Venom. Missions are linear and include few surprises. Most take place in large, multi-platform areas where you need to follow a colored indicator towards your next goal. The catch to each level is the Threat Meter that slowly rises during missions. As you defeat enemies and rescue civilians, the meter drops while failing to do these things in a timely manner raises it. If the meter gets too high, you have to start over.
Patrol missions work the same as Story missions, only the areas are bigger and require more backtracking. Compared to the story missions, these tend to be a little more difficult, though they are worth the extra effort. Defeating enemies earns Hero Points. Once you have enough points, you can purchase new moves and upgrades in the store.
The big downside to the entire game is that it is short. Depending on your skill level, it takes anywhere between 8 - 12 hours to complete the entire Story Mode. Replay value comes in the form of items hidden in each level. In addition to meteor shards, copies of the Daily Bugle and spiders are hidden in various locations. Finding all three in a level earns bonus Hero Points and other unlockable content. You can also go back through completed missions with a time limit or complete races found in the city.
Multiplayer is also available, though none of the modes are particularly exciting.
