This helps to diverge Zero from simply being a melee-version of X by giving him a system of combat that feels more like a reward than a self-imposed challenge.
Zero may get fewer armor upgrades, but has a unique combo system that allows him to chain together slashes and special techniques, allowing skilled players to pull off rapid combinations that feel right out of the Marvel Vs. Furthermore, these parts can be mixed for new effects unique to each combination, encouraging experimental gameplay. The new Hydra water-elemental armor for X seems to focus on survival and damage mitigation with a buster that can shoot through walls, a jump upgrade and item-pulling ability, whereas the Phoenix Armor focuses on offense with a burning dash and rapid-fire charge shot when below a certain threshold of health. Upgrades for X's armor are nothing new, but Corrupted offer a new take on upgrades. Related: Zero's History With Mega Man X, From Sidekick to Hero
