We recommend reading the Quick Guide first that will make things mentioned here easier to follow. Map callout areas have been used for referencing. We have tried to make points that can be applied in Freelance/Squads. However, it can be difficult to apply some points in Freelance.

Based on Figure A open gusher C and D first. If both gushers are high then the Goldie is in either B, G, E or F.
Based on Figure B if gusher C is low and D and G are high then the Goldie is in A.
Based on Figure C if gushers C and D are both low then the Goldie is in H or I.
Based on Figure D always open gusher F first if it is high then the Goldie is in C.
Based on Figure E if gusher F is low then the Goldie is in A, B or G.
For safe positioning, weapons with a fast fire-rate and good DPS should be in this position with slower weapons on the platform. This is the safest way to play this wave. See Figure A
A useful strategy to maximise eggs by pushing up and splatting Chums early, while letting players at the basket splat the Goldie. See Figure B
If a Griller spawns from the beach, docks or under the grates the targeted player should stand on the platform next to the basket. The others can also stand here and shoot the tail as the Griller comes right next to the basket. One player can go to the slope and splat Smallfry so they don't bother players who are shooting at the Grillers. See Figure A
If a Griller spawns from the pier the targeted player should move to the bottom of the perch area while the others stay at the basket platform. As the Griller passes by the basket the other players can shoot the Griller easily. If that targeted player stays on the platform next to the basket it can be very difficult to stun the Griller. See Figure B
When the Griller spawns from the pier this shows the angle on how to stun the Griller easily from the basket platform. In Freelance if you are the target it can be safer to lure the Griller the long way by jumping to mid or the overlook ramp. The Griller will take a longer route to basket through mid. See Figure C
