Metal Slug

Metal Slug 3D maintains many features from the 2D entries; characters use an arsenal of various guns, grenades and explosives, and vehicles. The game also introduces full three-dimensional movement to the series to coincide with its 3D presentation, which uses super deformed characters.
Each character begins with a full proficiency in different categories. For example, Marco starts off with a full Hit Rate skill while Fio starts with a completely upgraded Pellet skill.
Another new feature is a grade system, which ranks the player according to their performance on each of the game's 12 levels.


Upgrades and customization are some of the largest new features. Players can upgrade each character's combat abilities, categorized into Pellet, Power, Hit Rate, and Machine. Playing through the game also awards Skill Points to the player, which can be used to upgrade 4 other abilities, which affect the amount of damage a character can withstand, their ability to evade enemy attacks, and more.
These abilities allow characters to increase the damage, "splash" radius, and accuracy of their weapons and vehicle handling, respectively.
