Another great PvP fighting game from Capcom! This game is essentially a more robust re-release of the Marvel VS Capcom 3 game, so if you already have a copy of that game, you don't really need this one. The only real difference to this game is the inclusion of more playable characters.If you are not familiar with Capcom fighting games, you may be a bit surprised, at first, as to how fast-paced this game is. It is possibly the fastest-paced game I have ever played. Each character has their own signature moves and combos that must be executed perfectly and at just the right time to maximize their effectiveness. Due to the high amount of skill needed to pull off these moves, some players may find it frustrating at first. They will most DEFINITELY find it frustrating if they jump into the fray against a skilled opponent. Seeing an opponent give your character a smack-down with a 50+ hit combo that nearly vanquishes them in one assault will be more than a little intimidating and humbling. This is a game that really takes some invested time to master, and Capcom HAS included the option to play a "Simple" mode, that will allow most players to pull off some devastating moves without fully learning the controls and the nuances of the game. Once players get the hang of the game play and learn the strengths and weaknesses of each character, the game becomes much more fun to play. This is a game where there can be tremendous swings in advantage within mere moments. At one moment it could like like you're getting blown out and the next moment you could be on top. This adds to the fun of the game for me. I don't like games that are too easy or require no skill to play.This game has three modes of play:1) Offline Mode: Just as it sounds, this is where you play against the computer (Arcade), play against a friend (Versus), play through an advancing story line (Mission), or learn the moves of your character in practice sessions (Training).2) Xbox Live: Once you feel as if you have an adequate grasp of the game (or have friends who are not-so-skilled that you feel like schooling, you can use this mode to go online and play against others.3) Heroes & Heralds Mode: This mode of play was not included in the actual release, but was a part of a free download from the company to expand playing options. In this mode you have 3 decks (A,B,C) each deck contains 3 slots for a card. Each card has a buff that will aid you in your fights by boosting a stat or giving your character the ability to do something it would not normally be able to do. You can choose to be a Herald of Galactus or a Hero of Earth and you collect cards to build up your deck as you win battles. Each side has particular cards exclusive to each side.In this game you have a variety of villains or heroes from each respective universe that you can choose to play as/against. (In a fight, you choose three characters for you "team" and you will fight against three opponent characters. You don't have to choose all characters from one specific universe, but can mix and match at will.) With the addition of 12 new playable characters compared to the original MVC3, there are a whopping 48 characters to choose from. The complete character roster is listed below, by side:MARVEL:New since MVC3: Ghost Rider, Doctor Strange, Rocket Raccoon, Hawkeye, Ironfist & Nova.Previously released: Captain America, Thor, Spider-Man,Storm, Wolverine, Deadpool, Magneto, Iron Man, Doctor Doom, Dormammu, Super Skrull,M.O.D.O.K., Phoenix, X-23, Hulk, She-Hulk, Taskmaster, Sentinel.CAPCOM:New since MVC3: Firebrand, Frank West, Nemesis, Vergil, Phoenix Wright, & Strider HiryuPreviously released: Ryu, Chun-Li, Dante, Trish, Crimson Viper, Viewtiful Joe, Spencer, Amaterash, Chris, Wesker, Zero, Tron, Morrigan, Felicia, Haggar, Arthur, Akuma, Hsien-Ko.As you can see, there is an incredible diversity of characters, here. While there are a few characters that are conspicuously absent (such as Megaman from Capcom and Green Goblin or Venom from Marvel), the appearance of several characters that have never been included in a video games before was really nice to see. Each character has several alternate costumes that can also be chosen. Some of them are comic accurate and some aren't, but it's a nice little touch to add a bit more diversity to the game. I would suspect that there will be a fair amount of Marvel comics fans who will purchase this game based solely on their love of these characters. In fact, I'd say it will be a safe bet that the majority of people purchasing this game will be comic fans.This game is a lot of fun to play, and any fans of fighting games are sure to love it. In my opinion, this is one game that is a MUST BUY title for the Xbox 360.This game has a Teen rating due to cartoon fighting violence, a few instances of profanity (mostly from the character Deadpool), and some skimpy costumes worn by a few of the female characters (Felicia & Morrigan). I would personally say that a "T" rating is the proper rating for this game.
