The Romket-178 is the Tier 1 shotgun of the Heavy class. It is a pump-action shotgun which excels in close quarters combat. Aiming for the head when using the weapon can help ensure that the player achieve a one-shot kill within effective range. The weapon is reloaded shell-by shell, which amounts to a very long reload time if the player has expended every shell in the magazine; one might instead top up the chamber after every kill, to ensure maximum lethality within closer distances. Firing the weapon in the middle of a reload also halts the reload.
Because of the weapon's low range, a long-range launcher such as the a HEV Mk 51 can be a strong pairing with the Romket. Like all other Tier 1 weapons, the Romket lacks armor penetration, making it a less practical choice one a player reaches higher-league gameplay.
