[h1]✒️Review [/h1] [h3]✍️Overview [/h3] Operation Darkside DX is a visual novel with resource management elements and turn-based RPG combat. You play as an evil doctor who must manage a laboratory to create beings capable of defeating the Holy Core Battlemaidens, and then corrupt and control them as well. The game is linear, requiring you to complete battles to advance the story. In between, you need to farm resources to power up your units and corrupt the Battlemaidens you capture. The anime-style art is not very detailed, being more simplistic and somewhat distorted, but it is still visually appealing. The game also features Japanese voice acting for all eight heroines and a large number of uncensored static sex scenes (76), though more than half of these are variations of others. Finally, it’s worth mentioning that this is the “deluxe” edition of the game, hence the “DX” in its name, since it includes all the DLCs. These add post-game content featuring a story section and two heroines who do not appear in the main story, as well as a series of extra battles with restrictions that make them more challenging than those in the main story.
Coin toss, but not for me. You get an MC who isn't allowed to do anything to them. You essentially play cuck corruption as everyone else gets to make out with the girls, but you. Artwork nice, gameplay descent enough considering the price. DLC fine. Using money to buy explosives and throw at the main girls to speed through okay... being stuck watching all of the girls make out with anyone else besides you? Nope. Which is a shame as I really liked the idea and the concept. Just hated how it ignored you.
[b]한줄 총평[/b] 정의로운 소녀들을 타락시키는 끈적한 배덕감과 훌륭한 수준의 한국어 번역이, 부실한 전투 시스템과 조작 편의성의 단점을 너끈히 덮어주는 가성비 좋은 하드코어 조교물. [b]플레이타임 기준[/b] 메인 스토리 클리어까지 약 4~5시간 소요. 모든 갤러리 해금 및 재화 파밍 완료 시 6~8시간 이상. (본편과 DLC가 모두 포함된 통합본 기준) [b]장점[/b] [list] [*]세뇌, 타락, 인체 개조 등 다크 판타지 취향을 다양하게 만족시킬만한 관능적인 이벤트 씬과, 캐릭터의 감정선을 생생하게 전달하는 훌륭한 풀 보이스 연기. [*]7명의 각기 다른 개성을 지닌 성핵전희들의 매력적인 캐릭터 디자인. 특히 이번 DX 버전에서는 일부 캐릭터의 연출 및 일상복이 개선되어 시각적인 만족도가 한층 높아졌음. [*]본편과 DLC가 포함된 완전판의 뛰어난 가성비. 여기에 텍스트의 미묘한 뉘앙스까지 자연스럽게 살려낸 고품질 한국어화 노력이 더해져 장르 팬들에게 언어의 장벽 없는 깊은 몰입감을 제공. [/list] [b]단점[/b] [list] [*]턴제 전투 시스템의 깊이가 매우 얕고 템포가 느리며, 오토 전투 버그 및 전투 후 수동 회복 강제 등 편의성과 UI 측면에서 낡고 불편한 기색이 역력. [*]히로인이 타락해가는 과정에서 겪는 치밀한 심리적 붕괴나, 타락한 동료들 간의 유기적인 상호작용 등 세밀한 감정 묘사가 부족하여 서사의 깊이가 다소 얕게 느껴짐. [*]스팀덱 구동이 가능하긴 하나 완벽하게 호환되지 않는 부분 지원 상태라 조작이 다소 불안정하며, 원활한 플레이를 위해서는 유저가 직접 스팀덱 버튼 매핑을 설정해야 하는 번거로움이 있음. [/list] [b]추가 의견[/b] 오퍼레이션 다크사이드 DX, 이 게임은 플레이어가 악의 조직의 닥터가 되어, 정의의 아군인 성핵전희들을 차례대로 포획하고 타락 군단으로 개조하는 턴제 RPG 기반의 조교 시뮬레이션. 뻔한 영웅 서사를 비틀어, 연구소에서 갖은 수단을 동원해 콧대 높은 히로인들을 쾌락에 굴복시키는 일련의 과정은 다크 판타지 성인물 특유의 끈적한 배덕감을 충실하게 전달. 특히, 일본어 음성과 맥락에 잘 들어맞게 번역된 한글화 덕분에 이러한 관능적인 분위기와 캐릭터들의 대사가 겉돌지 않고 찰지게 와닿다고 느낌. 이 게임의 진정한 가치는 얕은 게임성을 상쇄하고도 남는 뚜렷한 캐릭터성과 몰입감 높은 연출에 있음. 히로인들이 육체적, 정신적으로 무너져 내리는 모습이 훌륭한 성우진의 연기와 깔끔한 한국어 현지화 텍스트가 맞물려 강렬한 인상을 남김. 다만, 천천히 조여오는 심리적인 압박보다는 물리적이고 즉각적인 수단에 의존하는 경향이 있어 스토리의 입체감을 기대하기엔 아쉬움이 남으며, 느릿한 전투와 후반부의 불필요한 노가다 파밍은 뼈아픈 단점으로 다가옴. 더불어 스팀덱 유저라면 컨트롤러 매핑을 직접 손봐야 하는 등 약간의 수고로움도 감수해야 함. 그럼에도 불구하고 7명의 다채로운 히로인, DLC가 모두 통합된 풍성한 볼륨, 그리고 망고파티의 정성스러운 한글화가 돋보이는 이 작품은 성인 게임 본연의 목적에 충실하게 부합한다고 할 수 있음. 다소 엉성한 시스템을 감내할 수 있고, 악당의 시점에서 정의를 무너뜨리는 매혹적인 쾌감을 좇는 장르 팬이라면 충분히 만족할 만한 수작. [b]추천 여부[/b]: [u]추천 (타락/세뇌 장르 선호 + 고품질 한글화 및 매력적인 보이스 중시 + 훌륭한 가성비)[/u] (깊이 있는 턴제 전투나 완벽한 스팀덱 호환을 원한다면 패스)
야겜으로써 충실합니다 성우 연기 좋고 히로인 타락해 가는 과정이 각자 개성 있습니다. 복잡하지않고 노가다도 심하지 않으며 즐길수 있어서 좋았습니다.
你他么别脱裤袜啊!!!!
가격대비 분량 겁나 많고 볼거 겁나 많은데 전투도 겁나 많이 해야됨 그림체가 좀 거칠긴한데 공장에서 찍어나오는 안꼴리는 미소녀 그림체보다는 나음 만족함
[h1]Operation Darkside DX[/h1] [quote] Follow [url=https://store.steampowered.com/curator/45434562/]Good Game Collections[/url] to check other reviews. Let's collect good games together~! [/quote] [h2]Summary[/h2] [quote][b]Patch is not required![/b][/quote] [b]Operation Darkside DX[/b] is an RPG eroge that focuses on capturing, re-educating, corrupting, and training heroines. The player will take the role of the chief scientist of the evil organization, the [b]Forren Foundation[/b], and capture the members of [b]Holy Core Battlemaidens[/b] one by one and turn them into combatants. The game is not very challenging. If the player cannot defeat an enemy, completing [b]Resource Gathering[/b] provides extra resources to strengthen the party. Besides the 3 default combatants, members of [b]Holy Core Battlemaidens[/b] will also become playable after successful training. Although every heroine has unique abilities, the character balance is kinda poor. Late game enemies have very high attack and defense, making [b]Yakumo Nayuta[/b] almost the only reliable damage dealer[spoiler] (especially during the DLC chapters, where the party is limited to only 2 members)[/spoiler]. The game has 76 H-scenes, which include themes such as defeat, corruption, tentacles, training, imprisonment, and scat…etc. However, most H-scenes focus on the heroines with combatants, monsters, or machines; the Doctor (the player) does not participate in these scenes, making the experience feel less immersive. Overall, this game is recommended for players who enjoy playing as a villain and capturing and training heroines. The ways to train heroines and the number of H-scenes will not disappoint! [h2]Pros[/h2] [list] [*] Decent story [*]7 heroines with different characteristics [*] Enjoyable battle mechanics [*] Various training methods to corrupt heroines [*] 76 decent H-scenes [*] Full voice acting for the heroine [*] Great English and Chinese translations [/list] [h2]Areas for improvement[/h2] [list] [*] The Doctor (the player) does not participate in any H-scenes which makes the experience feel less immersive. Adding some H scenes related to the player (like captured heroines who still taunt the player) would improve immersion [*] Although all heroines have full voice acting, the voice volume is inconsistent. It sounds like the voices were recorded at different times and locations. Adjusting the audio balance would improve the overall experience! [*] The healing items in the game only restore a fixed small amount of HP and cannot be used on other party members, making them almost unusable in the late game. It would be better if they could be used on any party member and restore HP based on a percentage [*] The character balance is poor, forcing the player to keep [b]Yakumo Nayuta[/b] in the party during the late game. Balancing the characters (especially heroines) better would improve the overall experience [/list]
中规中矩,玩家是类似修卡集团的,抓捕魔法少女,然后人格排泄,洗脑调教成成战斗员。还把排泄出的人格软体改造成飞机杯一样的装备。cg全是静态ppt,调教花样倒是多。给个七分
玩法超爛 又無聊 錢難賺 逼農怪 圖也少 花錢活受罪
게임 태그 - 인격배설 - 사지절단 - 최면 - 기억 소거 - 팽유 - 모유 - 촉수 - 개조 - 모판화 - 니플퍽 - 능욕 등 그림체가 안꼴린다는 평에도 불구 내 취향에 너무 잘맞는 게임이라서 구매했고, 또 매우 재밌게 플레이 했다.
