BrickBattle Guide: Slingshot
The worst weapon in the game? Useless? When I started playing it definitely seemed that way. However, I've been using it more recently and my opinion is slowly changing. Here's some things to think about:
Damage Output: A single slingshot bullet does not do very much damage. However, the slingshot has a very high rate of fire. If you are fast you can shoot more than 20 slingshot projectiles in the same amount of time that you could shoot one superball. If you are accurate, hitting your enemy with 20 slingshot projectiles will do more damage than one superball hit.
Accuracy: Unlike the superball, the slingshot automatically calculates the angle to use to hit the location under the targetting cursor. So if your enemy is behind a wall and only his head is showing, it is not hard to get him with the slingshot. Here's a fun thing to do: in Chaos Canyon get to the top of the big battle cube and shoot people below with a stream of slingshot bullets - it's easier than trying to nail them with rockets, since rockets move so slow and can be dodged.
Defense: If you rush at me head-on with the rocket launcher, and I am using the slingshot, I'm going to win 80% of the time. This is because your rocket will often hit one of my sling bullets and detonate before getting anywhere near me. All the while, you will be taking damage from my bullets. This defense works against superballs too (though is less effective). I see a lot of noobs only using the rocket launcher. This is silly - I'll TOTALLY PWN you with the worst weapon in the game if you do this. The only thing you can do against someone who is up in your face with a slingshot is to use the slingshot against him, fire faster, and fire more accurately.
