Trembler became a standard unit in Oblivion Hunter Drell Military division but rare in Oblivion Hunters itself. It doesn't deal a lot of Damage but it is compromised by its accuracy and ammo capacity which is doubled. The weapon became effective in later years of Inquisitor Crisis. It is also was modified to a level of more retractable parts to be the smallest and most compact weapon in Galactic History. Alliance bought enough of this weapon to give it to full army.
