We managed to corner the team to confirm at least two new styles. The new Viper style will poison your enemies and cause damage to them slowly over a period of time. The new Iron Palm style is a very slow attack but makes up for it by being unbelievably devastating. We've also confirmed that there will be a couple of new weapon upgrades you can get towards the end of the game but the team wasn't ready to provide us with any concrete details about them.
