Hyperdimension Neptunia mk2 (超次元ゲイム ネプテューヌ mk2, Chōjigen Geimu Neputūnu mk2, lit. "Super Dimensional Game Neptune mk2") is the second installment to the Hyperdimension Neptunia Series on the PlayStation 3 and the reboot of the first installment, Hyperdimension Neptunia. This game follows the story of Nepgear, the younger sister of Neptune and the CPU Candidate of Planeptune. The game features both returning and new characters, and takes place in a alternate world from the first title.
Just like its predecessor, Hyperdimension Neptunia mk2 received a remake on the PlayStation Vita titled “Hyperdimension Neptunia Re;Birth2: SISTERS GENERATION” that was released on March 20, 2014 in Japan.

The year is 20XX, and in the wake of Arfoire, who was previously defeated, a force known as ASIC (Arfoire Syndicate of International Crime), a group solely dedicated towards the deceased Arfoire, has risen, led by CFW Magic. Over the years, the influence of ASIC has become increasingly powerful, currently affecting many residents of Gamindustri. As such, in response to the threat, the CPUs and Nepgear travel to the Gamindustri Graveyard to combat ASIC. However, when they are overpowered and captured, Compa and IF come to their rescue and free Nepgear. With the fate of Gamindustri and the CPUs in their hands, the CPU Candidates must free their sisters and destroy ASIC.

Hyperdimension Neptunia mk2 takes place in an alternate Gamindustri from the first Hyperdimension Neptunia game. Instead of floating continents like in Hyperdimension Neptunia Re;Birth1 and Hyperdimension Neptunia, this Gamindustri is comprised of landmasses in the middle of the ocean.
There is a main continent upon which Planeptune resides in the western region, Lastation in the eastern region, and Lowee in the northern region. In the southern region of Gamindustri, Leanbox resides on an island away from the main continent. There are also several other islands surrounding the Main Continent and Leanbox.

The Chirper System allows the player to gather information and view events. By checking the chirps of Gamipics that have an event symbol, the player can view sub-events that increase affection between Nepgear and her party members for Lily Ranks, and potentially obtain items or skills.
Lily Rank is a system that measures the level of friendship between Nepgear and her companions. You can improve Lily Ranks by viewing events and fighting in battle together.
If the Lily Rank between certain characters is high enough, the player can unlock new items to develop, or even influence the game's story.
You can alter Nepgear's CPU outfit textures by using Costume Canvas Textures saved in the PlayStation 3's photo gallery. This will change her in-game appearance when she transforms into her Goddess form.
The battle system in Hyperdimension Neptunia mk2 is turn-based by unit, where each character's turn comes based on their speed. Characters spend AP to attack enemies or use an item, or may execute Skills which expend both AP and SP.
Each allied unit may move within the battlefield as far as their movement range allows, denoted by a blue circle on the ground. Equipped weapons, Skills used, and both position and distance to their targeted foe are all attributes to pay attention to.
CPUs and CPU Candidates can activate HDD by expending SP. By transforming, the character will access their Processor Unit's untapped power; as a result, their stats will boost significantly. However, there is a downside—each turn will drain SP until it is depleted, at which point will then automatically turn back into their human form.
Much like the first game, Hyperdimension Neptunia mk2 also uses a Combo Branching feature that allows the player to customize combos to buttons, but in a simpler way. There are three types of attacks: Rush (high Hit Counts), Heavy Hits (high HP damage), and Breaks (highest damage to GP).
A regular attack's range and power varies based on what the character equips. The 1st attack is fixed, while each of the buttons for the 2nd to 4th attacks can be set up using whatever Commands you have learned. You can create up to a 4-attack combo.
If you execute a combo in a certain sequence and spend more than a certain amount of AP, an EX Finish will automatically activate at the end of the combo. If you keep pressing the buttons marked with the EX icon, you will be led to the execution of a powerful EX Finish.
There are two major functions to utilize in dungeons: Treasure Search, which reveals secret items hidden within each dungeon, and Symbol Attack, where you strike monsters wandering around dungeons. If a Symbol Attack is successful, the player can start the battle with the advantage of an SP bonus. If the character has a high enough level relative to the enemy, they can defeat the monster instantly using a Symbol Attack without fighting at all.
Dungeons are filled with various objects. If an event is available in the dungeon, there will be a Sharicite Symbol that will initiate the event upon being approached. There are also Save Points, Item Boxes, and Gathering Points.
Item Development allows the player to develop new consumables and equipment. In order to create, the player requires two things: Product Proposals and Ingredients. Product Proposals act as the blueprint for the item while the Ingredients are needed to actually develop them. Some items require a certain amount of Lily Rank between Nepgear and other characters in order to be made.
