About
Mecha Harem: Bonds of the Abyss blends thrilling bullet-hell mecha shooting with lewd H-interaction gameplay. Pilot your fighter to dodge dense bullet patterns, defeat powerful bosses, and gather fuel for your mothership—the last hope of humanity in space. Bond with the beautiful heroines aboard your ship… and even the sexy female bosses you conquer.

An unlucky loser gets struck by lightning and finds himself isekai’d into a post-apocalyptic universe. With help from girls of various professions, he boards the mothership and accepts missions to search for resources. Piloting his mecha, he fights through galaxies, defeating enemies and adding each beauty to his harem. Beat a stage boss, return to your ship, and enjoy exclusive H scenes with undressing, speed control, and position switching for maximum immersion.



Intense Bullet-Hell Action – Three mecha modes, energy drops from enemies, and devastating firepower bursts for ultimate satisfaction.
Character Unlock System – Defeat bosses to unlock new heroines, advance the story, and open up more H interactions.
Rich H Content – 10 romanceable characters and 16 high-quality lewd CGs to satisfy both your eyes and collection instincts.


We know not everyone is comfortable with fast-paced shooter games,
so we’ve included a small hidden trick for those who need it:
👉 After entering a stage, press G
👉 Your ammo will be instantly refilled
⚠️ Please note:
This trick significantly lowers the difficulty
and may reduce the intended combat tension and challenge.
If you want the full bullet-hell experience,
we recommend using it sparingly — or only when you’re truly stuck.

一群壞人(指那群給好評的),這款遊戲要是玩得下去還給好評的,只能說明沒吃過好東西。
5+5=10个角色,每个角色1-2个动作,大概15个左右动作,你要打4关才解锁1个动作。大概打了1个钟,解锁了6个动作,那必须差评了,如果每个角色增加到3-5个动作,那我会改好评。这个我也不退款了,画面还是可以的,虽然可能是AI的,但是AI的画面也不错
遊戲很消耗時間,越後面關卡越難,但是你的戰機卻不能升級,好好加油
有點無聊
[h1] 机战后宫 ~ 深渊羁绊:这打飞机多是一件美事啊[/h1] 游戏玩法是通过操控宇宙飞船在躲避敌人射击的情况下将她们击毁,击毁他们的战机会掉落各种强化或者增加分数的道具,又闪避弹幕的按键,击败敌人会涨能量条,能量条满了可以释放超级能量,游戏中还有导弹可释放 游戏共有10个角色,16个动态手绘步兵CG,CG质量还是很不错的,可自选择全裸还是穿衣服跟内衣等等,自由性还可以,体位跟各种花活也不赖,实用性拉满 游戏剧情是发生末日后地球炸了,世界上只剩下一个男的跟一堆饥渴的女人,我们要和队友并肩战斗发生好感事件的同时也要调教被击败的敌人首领,整体走向是后宫 游戏每一个boss都有12个小关,对应五个不同的星球,基本每个星球都能解锁3个CG,解锁的关卡也在飞船中标明了,这点很不错 但实际游玩下来会感觉有点难受,每一关的节奏较慢,且没做全解锁,只能手动慢慢打,而敌人的花样也确实是较少,同时发射的子弹数量也有上限,爽感不怎么够,但也很好 游戏每一关开局按G可以直接满子弹数,稍微轻松点 总的来说虽然有点小问题,但毕竟游戏CG的质量不错,而且游戏也还算好玩,所以过程其实还是挺舒服的,角色的设计很色,喜欢后宫走向和平面射击类游戏的玩家推荐可以尝试一下,也希望制作组能优化一下战斗节奏 [quote]欢迎前来关注「 [url=https://store.steampowered.com/curator/45353266/] 𝗞𝗼𝗶𝗺𝗶𝗮𝗼🍁」 [/url] [u][b] 采撷旅途之叶,铭刻生命之诗[/b][/u][/quote]
總結:橫向卷軸闖關射擊小作品,瑟瑟多實用低,推薦折扣買。 = = = = = = = 。重點整理: > 射擊還算不錯,可空白鍵迴避、右鍵強力飛彈、Q鍵氣力滿啟動追蹤射擊。 > 官方內建小作弊按鍵,可降低不少難度。 > 關卡數很多,但卻是多到有點煩,且多數為沒啥意義的小關卡,且變化都不大。 > 基本無劇情,女角多且有動態立繪,畫風不錯,艦橋音樂好聽。 > 瑟瑟為步兵,免布丁,有鑑賞設計,無法急用,瑟瑟種類多(主要是女角多)。 > 演出為短動態,可開關衣物內衣飾品,並有不同階段按鍵,整體演出較可惜,實用度較低。 = = = = = = = = = = = = = = = 。建議 > 關卡數建議大幅縮減,每個星球從15關刪減至9關。 (小關卡太多沒意義只會增加玩家煩燥的心情...) > 關卡長度應該拉長,一般小關卡才1分鐘左右的長度實在不夠玩。
没有升级系统后期特别难受
动画还行,可是作为STG类游戏实在是太无聊了。。。虽然可以开局点G把子弹等级升到最高,没什么难度,但是还是玩得我犯困,把第二大关通了我是真玩不下去了。说真的直接点给个解锁全CG吧,反正你游也没什么剧情,无非是每关的队友或者BOSS说点没啥感觉的骚话。。。。 可惜了这么好的立绘了。
教官換我來教導妳了
希望后续能更新更多
