Omega Labyrinth

Gameplay

Omega Labyrinth is a roguelike dungeon crawler role-playing game. The dungeon is randomly generated; each time Aina and her accomplices enters the dungeon, its map, monsters, and available items change. As players move within the dungeon, the monsters also move in a turn-based fashion. Players accumulate experience by defeating monsters and characters become stronger as they level up. If they leave the dungeon, the characters are reduced back to level 1, and all items are lost when the health bar reaches zero. Thus, missions must be completed all in one go. The goal of the game is to search for and obtain the "Holy Grail of Beauty", whilst defeating monsters and avoiding traps through utilizing items, armor, and weapons.

When entering a dungeon, players can either choose another computer-controlled character to act as their partner and enter with them, or go in alone. Although partnering up has tactical advantages in battle, it is also more risky, as the partner's items are also lost when the team gets defeated. Through defeating monsters in the dungeon, players accumulate Omega Power (ωパワー) in addition to experience points; this increases Aina's chest size. This is accompanied by a increase in stats and if Aina reaches maximum Omega Power she enters "Hatsumune Mode", greatly powering up her status. When leaving the dungeon, Aina's chest returns to its normal size, though accumulated Omega Power can be used to purchase items.

Items obtained in dungeons are initially unidentified, with their name and effects not known. They need to be revealed using Omega Power, with an animated sequence where the player places said item between a characters breasts and shaking achieving this. Any character can be selected for this sequence, allowing players to choose their favorite. Players who do not wish to go through the scene may choose to skip it entirely. Players can also choose to strengthen their characters through the "Faint in Agony Awakening (悶絶☆覚醒)" system, which is triggered by special dungeon items; this leads to one of the girl characters going into an "excited" state. Touching her during this time allows Omega Power and status increases, and are unique to each character.

In dungeons, players can also find "panties" and "bras", which can be equipped to increase the defense of the characters along with weapons and shields. Combinations of these can also trigger special effects. Various categories of weapons are obtained through dungeon exploration, this includes swords, lances, axes, sickles, and katanas. Items can be synthesized in dungeons using Omega Power to strengthen them. As players progress through the dungeon, characters may sometimes be captured by monsters and tapping the screen is required to free them; this provides opportunity for fanservice, as well as screenshots of characters upon falling into a dungeon trap.

Omega Power can be spent and various items purchased at the in-game shop. The game features downloadable content which can also be picked up at the shop.

Characters

Plot

The game is set in the Anberyl Girls Academy, where a rumor of a "Holy Grail of Beauty (美の聖杯)", an object said to be able to grant any wish, has surfaced. It is said to be hidden in an ancient cave that is only open on the school's founding day. Thus, at the beginning of the game, several girls have come in search of the mysterious grail, with protagonist Aina Akemiya setting out to find the grail in order to increase her chest size, which is smaller than the other girls'.

Beginning the game's storyline, Aina and Nako head into a nearby dungeon in order to find the grail but are immediately separated. However, luckily Aina then meets the fairy girl, Pai. Pai explains that inside the dungeon, Aina will encounter monsters, and each one she kills will release Omega Power, a powerful source of energy which strengthens her stats and also enlarges her bust. However, upon leaving the dungeon, the Omega Power is dispelled and her chest returns to their normal size.

Promotion and development

The game was first announced in August 2015 through a teaser website, with additional information being later released in a Dengeki PlayStation issue. A debut trailer was subsequently released, and a second trailer was afterwards released in late October. Characters were teased in a series of silhouettes on Dengeki Online. Initial copies of the game include the "Lightning Malance" weapon and "Butt Shield" armor; unlike the other in-game equipment, these can be repurchased upon losing them in a dungeon.

Reception

Four Famitsu reviewers scored Omega Labyrinth 7, 7, 7 and 8 out of 10, for a total score of 29/40. The game sold 25,000 copies during its first week on sale in Japan.

Richard Eisenbeis of Kotaku summed up the game as "an odd mix of breast-filled fanservice and unforgiving dungeon crawling." He wrote that players who enjoy fanservice or challenging gameplay may like Omega Labyrinth, but the death system (where missions must be completed in one go) and limited item capacity were criticized as too difficult and too frustrating, respectively. The game was compared to the Senran Kagura series by Sato of Siliconera.
