Strategy to Easy Win the Rocket Doom Event

So, Rule 1: When you take a point, you stay on it and defend it until the end (this does not apply to the point closest to the spawn)
Rule 2: When you defend a point, you just stand there and shoot at the nearest enemies.

At the start, you are divided into two teams: Right and Left. The Right goes to the right, takes the point closest to your spawn and goes on to capture other points, following rules 1 and 2.
And the Left team goes to the left and captures all the points on the left, following rules 1 and 2.
