"Caught in a War between gods. Humans must make a Stand. Which Side will be chosen? Peace or Anarchy?"
Shin Megami Tensei IV Apocalypse, also known as Shin Megami Tensei IV Final in Japan, is a follow-up to the fourth numbered game of the Shin Megami Tensei series developed by Atlus for the Nintendo 3DS. This game takes place in an alternate timeline from the previous game.
Shin Megami Tensei IV Apocalypse was first revealed by Atlus on October 5th, 2015 in the Japanese gaming magazine Famitsu as Shin Megami Tensei IV Final along with the main keyword of the game "Deicide." It is produced by Kazuyuki Yamai, with Masayuki Doi as character designer, Ryota Kozuka as composer and Kazuma Kaneko as the setting planner and demon designer. The reveal image shows Navarre as a ghost alongside the other main characters. In an interview with Famitsu, Yamai stated that "We’ve looked over a lot of player feedback from Shin Megami Tensei IV and we're making improvements everywhere we can, even to things like controls and demon conversations—there is a lot of reconsideration and reforming going on. We're aiming to make the number one RPG for 3DS, so we’re paying attention to every detail. We're making it so that even those who didn't play Shin Megami Tensei IV can enjoy this game." Further details on the game were revealed in a Niconico stream on October 11, 2015.
Title change of North American version
Atlus U.S.A. explained the reason behind the change of subtitle from "Final" to "Apocalypse" immediately after the official announcement of the North American localization. While the USA staffers are aware that "Final" was already known to the series fans, the new subtitle was chosen to attract audience beyond the established fan base while still keeping the letter "A" prominent to be placed over the anarchy symbol as in the original Japanese logo. Other rejected suggestions include "End War" and "Holy War." The opinion to drop "IV" has been discussed more than once due to the precedent of Shin Megami Tensei III: Nocturne dropping "III" from the North American localization.
- Nanashi is capable of choosing which seven different partners to join him in battle, with them each specializing in a different role. There is an assist gauge at the bottom of the screen which fills up one point at a time as the chosen partner acts. Certain responses to a boss's question will grant extra assist points, easily filling the gauge to maximum. When the gauge is full at eight bars, the enemy side's turn is interrupted, partners with healing or stat buff skills will act once and then a powerful joint attack on all enemies follows. Afterward, random party combatants are granted the Smirk status, and the gauge is depleted to be charged anew. Partners also use their own demons to help with combat.
- Certain skills have additional effects when the user is under the Smirk status. For example, Light and Dark spells now primarily inflict damage which are effective against bosses as well, but their instant death effect only activates during Smirk; "King Bufula," an all-enemy moderate ice attack which is exclusive to King Frost, will debuff defense in addition during Smirk.
- The negotiation system has been updated; A demon who has abandoned the previous negotiation will take up where the talk has left off if spoken to again, rather than merely starting the negotiation all over again.
- Demons may have special Skill Affinity stats, that boost the properties of specific skill types; demons using skills they specialize in will result in the skill dealing more damage or costing fewer MP; conversely, demons with bad affinity for skills will do less damage and consume more MP on use. Resulting enhancements or disadvantages on skills are similarly proportional to ranking up individual skills of the previous protagonist or Nanashi via Whisper event.
- Estoma now creates a barrier around Nanashi rather than being channeled into his blade. A shortcut to cast Estoma instantly was added to the bottom left of the lower screen.
- User interface has been enhanced completely:
- The ability to rearrange the skill order of both the protagonist and his demons was added to the Party menu.
- An icon has been added to denote if the enemy demon has been registered in the Demonic Compendium.
- A filter to define a range of result levels was added to the Fusion Search. (1~9, 10~19, etc.)
- Utilizing the Mapper on the bottom screen to navigate the map pauses the overworld, allowing map investigation without being interrupted by encounters.
- The next destination of the current main quest is denoted in the map with a red flag icon and can be centered on by the press of a button while using the Mapper.
- Ability to zoom in or out in the overworld map was added.
- Partners will recommend the player to persuade a demon who has not been registered yet, and comment on the overall party status occassionally (e.g. pointing out someone in the party is Sick or suffering from Poison).
- When obtaining a relic, its expected selling price is displayed (except Relics gained as Quest rewards).
- Demons making vocal noises while attacking or hurt (similar to Shin Megami Tensei III: Nocturne).
