Rule: The character moves in liquid according to special movement rules. <a id=\"variant-mv-070\"></a>\n- Air supply. Rule: The length of stay under water limits the route and the search for safe points. <a id=\"variant-mv-071\"></a>\n- Underwater breathing. Rule: Upgrade removes air restriction and expands depth exploration. <a id=\"variant-mv-072\"></a>\n- Underwater dash. Rule: Acceleration helps overcome currents, distances and special obstacles. <a id=\"variant-mv-073\"></a>\n- Buoyancy control. Rule: The hero dives, surfaces, or maintains depth using a special ability. <a id=\"variant-mv-074\"></a>\n- Protection from heat and cold. Rule: Equipment or ability allows you to pass through temperature-hazardous areas. <a id=\"variant-mv-075\"></a>\n- Protection from poison, acid and infection. Rule: Sustainability removes or reduces harm to a certain environment. <a id=\"variant-mv-076\"></a>\n- Traveling on dangerous surfaces. Rule: The ability allows you to step on spikes, liquid or other special material. <a id=\"variant-mv-077\"></a>\n- Overcoming sand and soil. Rule: Digging or swimming through the material opens up additional routes. <a id=\"variant-mv-078\"></a>\n- Light as a condition for survival.
