MegaMan X4

MegaMan X4 is the fourth game in the MegaMan X series (as obviously implied) and the first to be natively developed for the PSX. The game is just as fun to play as it's three predecessors and includes several new elements to the gameplay. The most major of these enhancements, besides the better graphics and sound, is that Zero, X's partner since the first game, is now fully playable and has his own separate story to follow. X and Zero get different powerups as well; X's are more traditional, being different weapons with their own ammo counters, while Zero gets techniques that don't depend on ammo like double-jumping or air-dashing. X is also able to get secret suit upgrades that make fighting easier, while Zero doesn't have any and has to fight at close range, making playing as him slightly harder, though his Z-saber does a lot of damage. While this isn't my favorite Mega Man X title, it's a blast to play through and has a lot of replay value with hidden secrets and upgrades to discover!
