About

You wake up aboard The Orpheus, a derelict warship lost in deep space and crawling with horrors. No memory. Only the instinct to fight and a voice urging you forward. The ship shifts around you, the enemies never stop, and survival means battling through blood-soaked corridors to uncover what lies ahead.
Set in a haunting, low-poly world with crunchy pixel textures, Moros Protocol blends fast-paced combat of classic '90s and early 2000s FPS games, the unpredictability of genre-defining roguelites, and the challenge of Souls-like boss fights. Battle relentless enemies and towering nightmares in a brutal test of skill and willpower. With procedurally generated levels, evolving threats, and intense action, survival is never guaranteed.
The ship is a war zone. The enemy is endless. The odds are against you.
You may be outnumbered, but you are not outmatched.
Moros Protocol combines relentless action with adaptability and customization. Shape your loadout and let the augments and weapons you find dictate your fighting style. And yes, you can kick your enemies.
Death is only the beginning. Learn, upgrade, and push further into the unknown. Each run is shaped by a combination of handcrafted environments and procedural generation. New layouts. New challenges to face. No two runs will feel the same.
A gritty, immersive world that blends retro aesthetics with modern rendering, creating a decayed sci-fi atmosphere. Dynamic lighting and eerie sound design heighten the tension as you explore the abandoned warship.
Team up with a friend for backup. Adapt and survive together as you battle through the nightmare. Experience the full game side by side, sharing the fight against the enemy.
Message from Pixel Reign: Moros Protocol has been a passion project that started back in 2010 as a concept, which we have been working on for the last 5 years to bring it to life. We are really excited to finally be able to share our vision with you and hope you enjoy it as much as we've enjoyed making it.
Moros Protocol is inspired by some amazing games: DOOM, System Shock, Binding of Isaac, and many other amazing retro-futuristic first-person shooters. Check them out too if you have not already!

PLEASE DESTROY ME MOMMY. Nah but in all seriousness this game is actually really good in like every way. 9.5/10
枪是真的好使,怪也是真的会冲脸。但是喜欢刺激和维稳弹药收益的建议冷兵器直接近距离硬汉搏斗
Ta guapo a nivel gráfico y a cuanto ritmo de combate, pero... se hace repetitivo bastante rápido, muy poca variedad de enemigos, entorno, armas, etc
Quite mixed feeling on this one. It has good gunplay and movement, visually it's pretty neat, music is nice and has a good vibe. The Sin Seeker is also wonderfully designed, curves and all. Had my monkey brain twitching. Sexy good, brain happy. That said, the rogue elements and procedural generation tend to weigh this one down, and the first few levels are painfully slow with its weaponry and enemies. I don't think the game is very hard - at least for FPS vets coming from arena shooters - so the momentum of the first section tends to sputter along before finally revving up past the first boss. The repetition of the levels is problematic because there's nothing really interesting to see past the first levels of each section. Progression systems are basically percent scaling on stats, and unlocking items each death. Weaponry can be hit or miss - some weapons feel great (like the shotgun, has good punch, nice work here), while others feel sluggish and weak (the one shot shotgun, wtf is that thing). Likewise, combat can be very satisfying here and there, especially when kicking explosives into monsters and watching everything combust, but there's an intense repetition to it all that's hard to maintain motivation with. There's a story, there's a good pair of melons and thighs to look forward to seeing, and the art is pretty good, but I can feel the weight of the environments and lack of interesting mechanics with its perks and progression that it's hard to maintain my blood circulation, slowly but surely losing firmness...what were we talking about again? Right. It's pretty good - side way thumbs up. The devs have a good knack for art and combat feel. Movement is pretty good too. Level design and maintaining interest sans busts and waist ratios need some work though. Glad I bought this one anyway, but shelving for the moment.
This is a roguelike for people with limited time. A game you can actually complete. Sure the skilltree is unexciting (1% increases boo). The art is nice but not particularly varied. Some playstyles aren't really viable (can't melee some bosses). The game is pretty shallow and the story is barely there. But the gunplay is fun, there's a good variety of weapons, hidden bosses are pretty cool, it's well optimized and affordable. I enjoyed my time with it. The horror vibes were cool at first but a sequel could definitely use more varied environments that aren't so damn dark.
我承认我是被屁股吸引购入这个游戏的,游戏其实还行,就是如果数值不行会相当坐牢。但数值上去了又显得像是那种无脑突突突的爽游,如果体力条这个设定直接去掉其实也还行,就当doom玩嘛,又不是不好玩。但体力条这个设定会让你觉得游戏角色不跟手,但这是个类doom,一间厕所能塞一个团的那种游戏,技术好无非是多做几分钟牢而已。另外不建议因为这个屁股入这个游戏,因为见不了几次这个屁股,而且这TM是个BOSS。想试试doom被做成rougelike的可以试试。
awsome game, guns are nice, bosses are nice, even the dodge is nice in this game, i wonder if there is a endless mode, if there is then that is a good mode for this game, if not then they should add it to this game
不是那种纯无双割草,更像是在有限资源下硬着头皮往前推进,每过一层都有种死里逃生的感觉。
一把趁手的武器对游戏的体验有着质的飞跃
玩久了以后发现,真正决定能不能活下来的是走位,不是火力。
