Its finally here I think. We have arcade mode.

What to expect:
1. More than this one minigame.
2. Co-op play possibly.
3. Might be accesible through main game (Like a place you go in).

We now have spawnable boats! These might spawn like cars but in water.
There are a few things we can learn from these screenshots.

This seens like a new boat. Maybe a captains boat?

This is a cool new quality of life feature, blinking! I hope it happens to NCP 'S also.

This is the best shot we got of the new speedboat! I hope its fast!

As you can see the boat is not touching the other boat but the push eachother. This could be a serious bug!

A totally huge secret waiting for me to make a guide about it!

This is a huge revamped island.

We might be getting a new monster possibly a Louise!

Pirate ships!!!! So Exited!

Looks like treasure in Canada! So exited to see whats there!

This tells me that the trailer took place either in the pyramid or the jungle.

There will be 4 tests to the treasure. 1. A zipline test. 2. A stepping stone test. 3. Not sure on this one. 4. The Reward.

This looks like some sort of creature or puzzle? Not Sure.

Possibly the end of the puzzle with the reward laying behind it. Hope we get tons of money.

Fishing is here! We will get some cool new things from this trailer.
1.
We will be able to control our fishing rod and pull it up.
2.
The fish will spawn on the boat after fished up.
3.
There are several different fishing boats.
4.
There are more than one size of fish.

This Guide Will Be Quickly Outdated When The Update Comes.
I Would Also Like To Apologize For The lack Of Guides. Hope This Will Tide You Over.
Thanks For The Support, Ari.
