Fish are NPC creatures that roam the map. You can find them litteraly everywhere, even in a Station's safe zone.
Fish levels range from 2 at the lowest to 133 at the highest (excluding boss fish), with many many different variations. Also the higher a fish's level, the harder it hits. The highest level fish hits around 4,000 damage per shot.
Boss Fish Edit
Boss fish are mean, tough, and hit hard. It can take up to 3 people to kill 1 boss fish. When the fish is killed, it respawns an hour later. Boss fish also sometimes have smaller fish guarding it, making killing the fish even more difficult.
