Pro You're able to test your skills against others via a ranking system
Brawlhalla offers a ranked game option if you're into competitive play. In ranked games, each player has 3 lives and you battle until one player loses all of them.
Every player has an ELO rating, essentially a number that shows your rank. Winning games will raise your ELO, while losing will lower it. Every player also has two other ratings: the Matchmaking Ratio (or MMR), which is hidden from everyone, and an ELO for the character they're playing.
Your MatchMaking Ratio (MMR) is a secret number that determines what other players you'll be playing, and how quickly your ELO will rise or fall with victories and defeats. The ELO for the character your playing has a distinct effect on your MMR - a character you're not as good with will place you against lower ranked people than the character you're best with.
Pro Tons of different ways to enjoy the game
Brawlhalla is a 2D fighting game where you choose a character and fight in matches that are one of the following: 1 versus 1, 2 versus 2, 4 versus 4, and 4 or 8 person free-for-alls. Every game mode has a different reason to love it, from the fierce competitive feeling of the one on one match up, or the all-out ridiculousness of an 8-man free for all, Brawlhalla has a way for everyone to have fun.
Pro Very rewarding gameplay
In game, some of the moves are completely over the top, and when you connect with them it's just so satisfying. There's not much quite like being deep into a game and pulling off a ridiculous combo that clinches the victory for you.
On top of that, fighting games inherently have a lot of room for improvement, even for the top players in the world, and Brawlhalla is no exception. You can spend hours practicing your favorite characters and still want to get better. After spending all those hours practicing, it's great to put the beat down on an opponent in true Brawlhalla fashion.
Pro Completely free to play
Brawlhalla's developers have a strict "no pay to win" philosophy. There's an in-game store where you can buy things like alternate looks for your characters, new taunt and KO animations, etc., but there's no power-ups, no new mechanics, nothing that would give someone putting money into the game an edge.
