About This Game

DRAINAGE: BLOOD SIGNAL

Descend into hostile arenas where every second counts. DRAINAGE: BLOOD SIGNAL is a dark, fast-paced first-person action game built around relentless enemy waves, weapon-driven combat, escalating challenges, and persistent progression.

⚔️ FAST, WEAPON-DRIVEN COMBAT

Fight with four distinct weapon archetypes: EXECUTORA, PUNHO DO INFERNO, CEIFADORA, and ARAUTO DO FIM. Manage ammunition, collect supplies, use abilities and dash movement, and adapt your approach as enemy pressure rises.

🔥 FIVE-MINUTE RIFT RUNS

Enter timed Rift encounters built around escalating waves, elite enemies, events, and a Guardian finale. Each run lasts five minutes, pushing you to make every fight and reward count.

👹 ENEMIES, ELITES, AND GUARDIANS

Face multiple enemy archetypes with different attack patterns, including melee pressure, ranged attacks, and summoning. Elite modifiers can change the threat, while multi-phase Guardians create a final test of survival.

🩸 BUILD YOUR RUN

Choose upgrades and combine card effects to create synergies. Reroll offers, banish a card from the current run, and adapt your build as the arena grows more dangerous. Orbs, events, and secondary objectives add risk-reward decisions between waves.

📈 PERMANENT PROGRESSION

Earn Paragon experience, improve attributes, track weapon performance, record run history, and work through campaign stages, missions, and achievement milestones. Permanent and seasonal saves are kept separately in the current browser-based build.

🌑 A WORLD STILL TAKING SHAPE

The project uses a custom JavaScript Canvas 2.5D engine, procedural room and corridor generation, and a material system for distinct environments. DRAINAGE is in pre-alpha: asset compatibility, visual presentation, balance, and performance are still being validated. Some features are partial, and the current build should not be considered a finished commercial release.

ENTER THE RIFT. SURVIVE THE SIGNAL. DRAIN THE DARKNESS.
