BrickBattle Guide: Bazooka
From ROBLOX Wiki
Also known as the Rocket Launcher, this is one of the slowest weapons in the game.
While having an instant-kill on hand is fun, be warned of the slow rate of fire, as well as the relatively slow speed.
I you score a direct hit to any part of a player's body, it means instant destruction. It also has splash damage, meaning you can blow off bits of an enemies body, such as legs, arms, etc. Beware: the same can happen to you, if you shoot it too close. Being the second most powerful basic weapon, it can also easily destroy structures, and clear an area of debris.
It takes a good bit of time (seven seconds) to reload, leaving you very vulnerable to enemy attack. The actual missile can also be interrupted with a Superball or a Slingshot round, which can also leave you in the open without a gun. The missile also has an extremely slow speed, and is thus easy to dodge. Unless your target is close, stationary, stuck or away from their keyboard, you shouldn't use the Bazooka.
A few tricks are available: If someone else is firing a 'zooka at you, build a wall in front of the missile, or dodge it. It goes slow enough it could miss a sloth.
Try to retaliate to anyone who has just fired a rocket with a superball or slingshot. You should score an easy kill if they are just going to run in a circle waiting to reload.
The rocket can be used to destroy bridges and ladders that someone is climbing. If you find yourself trying to defend PilotLuke's Battle Cube from attack, the easiest way to defend the rim is to fire a missile at the two purple stairs and drop a bomb on the black set.
