Fight Crab 2 builds upon Fight Crab's control scheme by adding the "Modern" control option, which is closer to a typical third-person action game. Live commentary is also broadcast over every game as an extra way to keep players on the same page. Crabs can also now learn skills that let them perform certain actions automatically. All of these help make Fight Crab 2 easier to learn and play.

Career Mode

Grow alongside your crab as you climb to the top of the Crab League together! Obtain all sorts of skills and weapons and raise your stats as you proceed through your crab's career. Win Ranked Matches to climb up the rankings, fight in Exhibitions to square off against terrible foes such as a farm tractor or a giant monster, or eliminate evil crabs in the name of justice in Event Battles to get the public to notice you! Once you've raised a crab, you can bring them to fight other players in online matches, or pass down their skills to another crab just starting their own career.

Multiplayer Mode

Play 1-on-1 matches with players from all over the world. Choose from Ranked or Casual Matches and meet up in rooms that can hold up to 5 players. In a Room Match, you can even set your own custom house rules!

Humans

In this game, you're not a crab. You're a human. Naturally. You can mount a crab to control it freely, or dismount it to pick up or throw weapons, or make use of stage gimmicks to support your crab. In team battles, even if your crab gets knocked out, you can still fight on if you mount your teammate's crab! You can also customize your appearance both in-game and by connecting to VRoid Hub to change your avatar to look however you like.

Weapons

Crabs can hold weapons in both pincers. From knives to chainsaws, to hopping on a motorcycle, to mighty tools such as drills and jet boosters, or fantastical weapons such as the Excalibur or Nimbus, crabs are adept at every weapon you can imagine.

Spells

Whenever you take damage, your Crab Gauge gradually fills up. Spend it to activate all sorts of spells, such as summoning weapons or obstacles, or simply shoot beams from your eyes. Use them to turn the tables in your favor.

Skills

Customize your crab with over 40 types of skills to choose from. Automatic Skills support your crab's movement, Visualize Skills add more information to the HUD, and Hyper Skills let you unleash ultimate moves by striking a cool pose, just to name a few. Even if you're a beginner, using the right skills could help you gain an upper hand against Fight Crab veterans!
