basic moves
Steve can Punch and kick at high speeds, and deals a fair amount of damage.
Pickaxe Thrust
Steve can slam his Pickaxe onto the battlefield ground, and send power blasting through the floor. This would take longer to use, so it would be riskier, yet more powerful than punching/kicking.
Sword slash
Steve could also quickly pull out a sword and slash his enemies. This would deal more damage than the basic attacks.
