Killing Momentum: Umbral Moon is a A brutal, high-stakes tactical RPG where a single mistake doesn't just cost you a turn, but spirals into a total party wipe. Master an evolved, unforgiving take on the "Press-Turn" system adapted for grid combat. This game promises that every challenge is fair, every victory is earned, and every defeat is yours alone.

Killing Momentum won’t hold your hand. It will give you the rules, show you the tools, and expect you to figure out a way to win. The core of victory lies in the Killing Momentum System, a snowballing action economy inspired by the legendary Press Turn system, adapted for a grid battlefield. This isn't just about damage; it's about making every action count, and every hit echo.
![]() | Dominate the Grid: Positioning matters. Utilize movement, crowd control, and powerful yet costly Co-op Skills to control the battlefield. |
![]() | Stack Momentum: Exploit enemy weaknesses and land critical hits to do more in fewer actions, enabling devastating, cascading combo turns. |
![]() | Pay for your Mistakes: Every action has a cost. Fumbles and blocks double that cost. A single mistake may end not just your turn, but your entire run. |

![]() | All killer, no filler Forget about grinding. Success relies on skill, not hours played. Nothing stops a master tactician from beating the game on their very first run. |
![]() | Narrative is power: Powerful Co-op Skills aren't unlocked through grinding XP. They are discovered through unique, character-driven skits in camp. Learning your team's story is how you gain power. |
![]() | More than chess pieces: The combatants on your team are not just pawns for you to command. Discover their backstories, the bonds they make, their goals and aspirations. These will subtly influence your path to victory... or tragic defeat. |

![]() | Tough but Fair: The AI plays by the same rules you do. It has the same stats. It can only beat you by out-thinking you. |
![]() | Smarter, not Spongier: Higher difficulty levels mean smarter enemy tactics, not inflated health bars. Even the bosses may have weaknesses. A loss is, truly, a skill issue. |
![]() | Face the Music: Journey to the corrupted Temple of the Umbral Moon, and the destiny of your team will unfold. There are multiple endings, and a happy one is not guaranteed. |

Test thousands of different team builds, hundreds of intriguing strategies, and countless ways to win or lose in this complete tactical package.
![]() | 12 Unique Combatants: Build your team from a diverse roster, ranging from tanky defenders to chaotic fools, each with their own personality, skills, and hidden depths. |
![]() | 100+ Active, Passive and Co-op Skills: Form the foundation of your strategy, with powerful Co-op abilities emerging from specific team synergies and shared narrative moments. |
![]() | 60+ Unique Status Effects: Unleash devastating debuffs on foes or enhance your allies with strategic buffs. |
![]() | 3 Distinct Journeys & 3 Unique Bosses: Each challenging your tactical adaptability, with secret battles and escalating narrative stakes. |
![]() | Uncover Every Story: Replay with different teams to unlock all Co-op skills, witness unique skits, and delve into the full, complex backstory of each character. |

The game WILL chide you for losing, shame you for making mistakes, and won't stop the insults even when teaching you to play. Dark, cynical humor is part of its charm, and it revels in it almost as much as it does in the killing. This is a game with personality, for players who appreciate depth beyond the surface.
Respect the game, master the momentum, and carve your way to the ultimate victory.
