1. Pick Lord Vraxx. This is the only hero with which you can learn the game inside out. He is great for getting to know the game mechanics and understanding the trick to winning.

2. Always use the lance. The pistols are useless in this game.

3. This step might be a bit tricky to pull off in the beginning, but will make you a true master at Brawlhalla if you learn it. For this step you have to continuously press A + RMB or D + RMB. These attacks are also known as SSIGs, standing for side signatures.
If you manage to continuously do SSIGs all game, you will quickly rise to the top as this is the best tactic out there.

(Optional) 4. Call your enemy a spammer after the match. This is usually a great way to assert your dominance and will help you improve quickly.
