The Minirocket Tube is a weapon manufactured by Megacorp in Going Commando, Going Mobile (as the Mini Rocket) and Up Your Arsenal multiplayer. It is an auto-targeting long-range missile launcher which fires fast and powerful rockets.
The Minirocket Tube could be acquired from any Megacorp vendor, upon reaching Dobbo, for 50,000 bolts. It could then be upgraded to the Megarocket Cannon with use. In challenge mode, it can be upgraded to the Mega Mega Rocket, and in turn to the Ultra Mega Rocket with use.
In Going Mobile it is bought at the Weapon Store in both Series 40 and 60, available at the start for 400 bolts in the former, but only for 2,500 and after completing Communication Station's second visit in the latter. It could be upgraded to V3 with use.
The Minirocket Tube is a long, dark green weapon with a large cylindrical barrel, a left-hand grip and an orange glow emanating from a vent on-top of the barrel. The Megarocket Cannon features a scope at the back, four nozzles rather than one, and an ammo magazine at the bottom.
Ratchet would have a grin on his face when he pulled out both the Minirocket Tube and the Megarocket Cannon.
In Going Mobile it still has a similar shape, but instead sports a silver color and red nozzle.
The Minirocket Tube fires missiles with a fast rate of fire, which reach long distances and have a moderate blast radius upon contact. Due to the strength of the missiles and its good amount of ammo, it is a very useful weapon. It is most useful against mid-size to larger enemies, including bosses.
The Megarocket Cannon has an even better rate of fire, better damage, and can be charged up by holding down to fire up to four rockets on a single enemy. While this can further improve its already strong damage, it is often unnecessary due to the already fast rate of fire of the weapon.
The weapon could be modified with the Acid Mod and the Lock On Mod. While the Lock On Mod provides little value for the player as it is already relatively auto-targeting and easy to use while strafing, the Acid Mod applies damage over time and can be very effective. However, since the Acid Mod does not stack, the charge shot ruins the damage efficiency of the gun. To get the most out of the weapon's ammo and damage, it is best to only fire one at a time and wait for the acid to do its damage.
The Mini Rocket is similar in use as to the Going Commando version, as they both rockets in a direct line. Unlike the Minirocket Tube, however, the Mini Rocket is incapable of aiming and can thus only hit enemies directly in front of it. It is somewhat powerful, especially at V3 and early on, but is later outclassed due to its low rate of fire and low explosive range.
