yeah after shooting the dog twice in the back "provided i stayed by the wall so he would rebound" i jumped over him right before he jumped so he would jump away from me. Then let him jump toward me twice. after that i jumped over him again and was able to turn around quick enough to shoot him in the back again. Main boss. Thats just luck. shoot as falling. land on top platform. jump before it goes away and shoot. Now he's hit twice and will throw random stuff. just try not to get hit.
first thing i found about the boss. Shot it in the back. wait by the laser so when it jumps it rebounds and is facing away from you. after the second shot it jumps low and not over you so i dont know what to do after that.. cant seem to get behind it
i thought maybe if a survivor died from being one shotted by a fast fat runner with a weapon then i could just die and restart with that guy back alive... What a pointless thought. cant get anywhere if even One of my dudes dies.. and its going to happen.. like you head going splat diving off a 20 story building
as soon as i noticed i was at the boss... i just sat and shot at 10 shots a second. didnt care about damage cuz i collected 300 bubbles worth without an upgrade
some tips. 1 For the love of Neptune don't hit a ring on the way down. 2 Make a perfect entry All the time even a nice one will sometimes take all your speed away. 3 don't lose your speed cuz you only have 2 minutes and you need every second. 4 keep moving and keep jumping swimming too long will hurt your time. 5 Get someone else to do it for you lol
