The Net Projectile can immobilize a target caught in it for a minute. After it wears off you have to wait 30 seconds before you can net the target again. The netted dino cannot attack, tamed or wild, nor can the owner ride the dino. If the dino is tamed it can be cut away by anyone with a Metal Hatchet, Sword, Pike , Metal Sickle or Tek Sword by hitting the affected dino three times.
The crosshair can be colored in three different ways when holding a Harpoon Launcher with the Net Projectile loaded:
Blue indicates no target is being aimed at;
Green indicates the target can be immobilized by the projectile;
Red indicates the target cannot be immobilized by the projectile, or that it is an ally.
