In Rainmaker, you only need to reach the enemy base a single time
to win. Because of this, the mode revolves around finding good
positions along a path to the enemy base.
Unlike Splat Zones and Clam Blitz, you don’t need to spawn camp
for any extended period of time; instead, the focus is on taking
guaranteed space as quickly as possible.
Take space quickly
In this mode, the objective moves as fast as you do, so speed is
absolutely essential to win. Pushes and counter pushes are most
effective when they happen immediately, so be sure to
bring a kit that can take space in the shortest amount of time
possible.
Be ready to intecept other players at all times
When you push into the enemy base, you’ll want to intercept the
enemy team as they come to defend so that they can't affect the
Rainmaker.
On the flip side, when the enemy team is pushing into
your base, you’ll want to intercept the Rainmaker so that
it can’t continue forward.
Since the Rainmaker carrier can rotate quickly, you’ll need to be
able to rotate just as quickly between defensive positions. Swim
speed is essential here.
