This only works on Kelp dome, you can use any of these 4 weapons of your choice, they are all light weighted so you’d run/swim faster (except for tentatek, but still pretty fast anyways)
when match starts, climb up to the perch, throw your sub at rainmaker shield while dropping down and climbing up to mid, then start shooting at the rainmaker shield and as soon as it pops, grab it and run on the left grid toward the goal, you may shoot once and kill the charger/splatling if they have one sitting on their snipes or run and pray.
Use lots of run speed and swim speed with opening gambit to be a lot faster for the first 30 seconds, if done correctly without dying, you could get a knockout in 20 seconds!
