The two new characters appearing in this version are Mega Man’s edgier rival, he of the big helmet, Bass! Alongside him comes a high-jumping and underappreciated plumber dressed in green called Luigi.
Possibly the biggest addition is one that might not be picked up on in the first viewing. Instead of leveling up in an adapted Mario style, each character now appears to level up the way that they do in their games, original powerups and all.
I am extremely excited for this. When it came out, I would play Super Mario Bros Crossover for hours at a time, and this trailer gives me hope that the upcoming big update will rekindle that love.
