History VideoGame / ShinMegamiTenseiLiberationDx2

** The last Hell's Park boss, King Frost, is a Level 100 abomination that Nulls ''everything'', and Pierce does squat against him due to his Hell Shield passive. The only thing that can even touch him is Almighty, and only the extremely rare Almighty (Phys) property (found only in Shiva A's Third Eye, Asura Lord's Slaughter All, Griffith's Blade of the Absolute, and the Skull Knight's Sword of Actuation) can crit him.

** The ''Anime/RebuildOfEvangelion'' event adds Unit 01, the Sixth Angel, and the Tenth Angel.

* LimitedMoveArsenal: Demons are limited to six skills and passives in total. While four of them are fixed, they can inherit skills into the other two slots; also, the most overpowered moves are often limited to a small amount of uses.

* CrossoverPowerAcquisition: How the {{Guest Fighter}}s are interpreted, essentially blank demonic matter influenced by contact with other universes into generating demons partially mimicking the original people and entities from those universes yet can be summoned in the Dx2 reality.

* {{Crossover}}: Every now and then, special events crossing over with other franchises will pop up, introducing the Liberators to problem sets beyond those of their own world. So far, the list of worlds includes ''VideoGame/{{Bayonetta}}'', ''VideoGame/DevilMayCry'', ''Manga/{{Berserk}}'', ''Anime/GhostInTheShellSAC2045'', ''Franchise/SonicTheHedgehog'', ''Manga/TheSevenDeadlySins'', and ''Anime/NeonGenesisEvangelion''.

* BonusBoss:
** The Kiwami battles are all insanely powerful Lv. 73 demons with huge HP reserves, modified variants of their regular moves, and a team of helpers tailored to maximize the boss' advantages and reduce the player's.
** Aura Gate 2 contains several demons who are much, much more powerful than the enemies and boss you find in the same floor. Examples are the demons you have to beat before you can create them via Multi-Fusion (the first of which, Parvati, is found on 7th floor), as well as the level 90+ Celestials you can first find on 8th floor of each of the five ten-story blocks.
** Events that use event area have one or two challenge battles that are significantly more difficult than the other battles in the same event.

** Players who log in during the first Manga/{{Berserk}} crossover event are rewarded with a Common archetype Guts, a Phys powerhouse if trained well. The second Berserk crossover gives a Common Zodd, whose playstyle is quite similar to Guts, only exchanging Guts' aggression for sustain.

** Berserker Guts has ''obscene'' STR and AGI stats; his main offensive move is Berserk, which is, bar none, the strongest single-target skill in the entire game, which has a real possibility of killing ''two'' enemies (it hits in two parts; if the first kills an enemy, the second will hit another one, ''especially'' since both attacks ignore Endures), plus Great Aim, which increases his accuracy by 20%; his Psychic Archetype has Death Blow, which increases the damage his Critical hits deal by 20%; and the Berserker Armor passive, which raises his Crit rate by an absurd 50% and reduces damage taken by 40%... but will also slap him with a 30% HP penalty at the end of the enemy turn, which will ignore his own Endure skills.

** [[spoiler:In the second, Vince destroys Elohim's copies to force them all to merge so he can destroy the last remaining one. To his horror, the last remaining copy isn't interested in interacting with the few surviving humans other than to KillEmAll, since they have not repented from the attitudes that brought forth Vanitas. He survives when Kokoro briefly sends him home as Elohim triggers its attack, but when he returns he finds all life in that world had been incinerated.]]

* DownerEnding: [[spoiler: The first two Take Back the City events. In the first, Shionyan discovers Susano'o, who'd been oppressing the few remaining humans and keeping Amaterasu sealed, was actually keeping them alive and giving them whatever meager help he could to cover up the truth that Amaterasu was dead, with his defeat killing what little hope remained in that world.

* {{Gainaxing}}: Subtle, but it's there. It's seen most clearly when the girls are in their swimsuits.

* MindRape: A mysterious letter draws Megakin, Vagit, Kazufumi and the MC into Cthulhu's dream in the ''Sleeper of the Deep'' event, keeping them in a state of sleep with constant nightmares. While in the real world they stay asleep for about two days, the group is forced to descend into the dream until they realize they're actually in a vision of R'lyeh. While everyone makes it out after the final door opens, the MC was the closest and the one who got the most exposure to whatever was on the other side. They awaken to convulsions and incomprehensible groaning, and are taken to a hospital for a month. In the end, they escape to the beach, and while they get picked up, their last line is Cthulhu's SignatureLine, as they give the ocean a last longing look.

** In addition to Talking and Fusing to acquire new demons, [[NecessaryWeasel there is now a gacha for demons]], which is standard mobile game trappings. However, Fusion hasn't been obsoleted, as many of the best demons can be obtained through Fusion, and many of the rarer gacha demons cannot be used as Fusion materials without a Common Archetype demon as the second material.

* {{Plaguemaster}}: Nergal's Plague of Babylon removes all enemy Barriers and inflicts Weak on them, all but guaranteeing any ailment that comes next will stick. Angra Mainyu's 16 Scourges slams the enemy with ''every single ailment in the game'' plus an unstoppable 25% HP hit. Samael's Panel 3 allows it to remove both magical shields and Barriers, clearing the way for its God's Malice. Motoko Kusanagi's Ghost Hack removes enemy Barriers and inflicts Mute and Bind. Similarly, David's Bemusing Rhapsody removes Barriers and inflicts Charm and Curse. Fafnir's retooled Golden Greed removes Barriers and inflicts Poison. Others such as Kabuso and Lilith have skills that instead chain when an enemy is inflicted a certain ailment (Poison or Charm, respectively) and follow up with another ailment casting (Charm and Bind, again, respecively).

** Alice A, Panel 4 Mother Harlot and Sabaoth reduce enemy MP if the enemy goes first, the first two draining one MP from each enemy at the start of each enemy turn and the latter hitting them with a one-time one MP reduction.

* ComboPlatterPowers: Some rare skills are essentially a combination of several lesser skills crammed into a single slot. Some of them are transferable, such as Elemental Cycle (which is Fire Boost, Ice Boost, Elec Boost and Force Boost rolled into a single package), while the rest are unique to extremely high-level demons, and non-transferable, such as Ardha's Sahasrara (Infinite Chakra's extra MP regeneration, Great Aim's accuracy bonus, Assassin/Serial Killer's bonus to all damage, and a healing bonus almost as good as Recovery Amp, all in a single Skill)

** Once you start fusing higher-grade demons, expect your painstakingly-hoarded millions of magnetites to go up in smokes.

** Elohim's brutal single-target Solar Flare attack will proc an offensive buff for his team and a defense debuff for the enemies and a follow-up [=AoE=] blast, and will fire yet another [=AoE=] attack the first time an enemy is downed each turn.

** Lilith A's Temptation, if successful, will follow up with a Charm effect. If at the end of her team's turn, there's at least one Charmed enemy, he Forbidden Fruit passive will add an extra Temptation free of charge.
