DrainSim: Become the City’s Hero, One Drain at a Time
Grab your rake, start the generator, and roll up your sleeves. DrainSim is an engaging and satisfying indie simulation game developed by CodePeas that turns the mundane task of unclogging drains into a physics-driven, strategic puzzle.
When a massive storm hits the city, the streets are swallowed by rising floods. It is up to you to restore order to the submerged neighborhoods by clearing blockages, redirecting water flow, and getting the drainage system back online. Whether you are a casual player looking for the immense satisfaction of watching floodwaters finally recede, or a simulation veteran looking to optimize your pumping strategies, DrainSim delivers a uniquely rewarding experience.
Strategic Flood Management
Plan Your Mission: Every job requires careful preparation. Before diving in, you must assess the terrain, the distance to your power sources, and the time of day. If you are working late into the evening, you will need floodlights. If there is diggable ground, bring a shovel.
The Right Tool for the Job: Start with basic tools like a trusty rake to pull debris away from grates, and work your way up to deploying heavy-duty submersible pumps, hoses, and gasoline generators to drain massive bodies of water simultaneously.
Dynamic Water Physics: The game features realistic, dynamic water simulation. Water flows, pools, and reacts to the environment in real-time. Unblocking a major drain creates a satisfying whirlpool effect as the neighborhood is slowly saved from ruin.
Progression and Upgrades
Unlock Better Gear: As you successfully complete missions and earn recognition as a flood-clearing specialist, you will unlock advanced tools and equipment upgrades, allowing you to tackle larger, more complex flooding scenarios.
Diverse Environments: Travel across a variety of unique, handcrafted levels—from residential neighborhoods to complex construction sites—each presenting new logistical challenges, tricky terrain, and unpredictable water flow.
Day-Night Cycle: Adapt to changing conditions. A flooded street looks very different in the dead of night, requiring you to carefully manage your portable lighting and generator fuel to get the job done safely.
