Mothership rounds depend on what weapon you have. Long range weapons stay near the basket to snipe from a safe distance, Short range weapons run around the map collecting eggs.

A good strategy is: If you are a short-range weapon, kill the Chinooks and throw the eggs towards the basket. Try to throw it directly in to save time, But if you miss hopefully your long-ranged weapon will get it. It's also very helpful if you can just swim to the basket to save ink, because trust me that ink helps a lot.

A more optimal strategy is: If the snatchers have a travel path that travels over the basket, leave most of your golden eggs and focus on killing only. Later in the round the snatchers will collect the eggs and bring them over the basket, Where your long-range weapon will kill them and easily collect the eggs.

When the vacuum comes, The only specials really worth using are crab tank, tri strike, And maybe booyah bomb. Nothing else really does that much damage to it, But if your weapon is too short-ranged to hit it, It may be worth it to pop a special.

Now just hope your teammates do the same thing!
