DrainSim, a challenging flood relief simulator, requires careful planning of rescue operations. Players will encounter realistic fluid behavior and a strict day/night cycle. Successful flood control depends directly on a thorough preliminary analysis of the terrain. Assessing soil density, calculating distances to power sources, and taking lighting into account are crucial preparation steps. The available arsenal ranges from simple hand-held tools to powerful submersible stations. Such technical diversity necessitates thoughtful combination of equipment.
