This game is flippin' awesome.
The focus has clearly been placed in multiplayer, there's around 8 different modes. This range from classics, like Team DeathMatch or Battle Royale, to capture the flag or the co-op survival mode, there's even a Soccer mode where each time must bring a ball to the other team's goal. Every mode has it's own rules, but most of the time it's reduced to beating your enemies to a pulp with your fists. Most modes also feature usable items, like Sniper Rifles or Shields, and some even place random enemies to add to the already chaotic nature of the game. If that wasn't enough, stages also have "events", usually a deathtrap of sorts gets activated and it's in your best interest to avoid it.
In order to unlock most characters, you'll have to go through the story mode. You get to pick between Leo or Jack, but after you are done with either campaign, you get to play as the other one and then go back to your original character for one last mission. In Story mode, you are thrown in a large area, where you must rack up points in order to open up story missions. You earn points by fulfilling Free Missions, which you can redo as many times as you want, or simply kill the endlessly spawning enemies. It's not as tedious as it sounds, finishing one free missions should be enough to open up a Story mission, and hey, Free missions usually provide variety, from a racing minigame to a shooting gallery where you get unlimited ammo. Story Mode also features a lot of cutscenes, and while the story is nothing special, the dialogue is totally off-the wall. The Blacker Baron in particular steals every scene he is in.
As great as the game is, it has one fatal drawback.... No offline multiplayer. This game was made with multiplayer in mind, and the multiplayer is nothing short of fantastic, but it can't be played offline. Not even Cage Matches(1 vs 1). This game has been marketed as a Fighting Game, not having offline multiplayer is unforgivable and crippling, tournaments can't be held, you can't play against your friends if they don't own a console, etc. Even sadder, and also proof of why it was a bad idea, the online is basically dead, save a few regulars that I came across as I tried finding matches. You can play the multiplayer modes with bots though, but it's hidden under the Training Menu, in the Simulation Option.
I absolutely loved this game, but as good as it is, not having offline multiplayer in a fighting game is just too bad. Single Player is entertaining, and after beating it you can use any character via Stage select, but it's not the same. Having bot matches is a small relief, but hardly makes up for the lack of offline. Still, when it's all said and done, it is a fantastic game.
9 out of 10.
