This is a guide/walkthrough of everything you can do in the map. If you are ever truly confused, you can also watch a playthrough of the original Tony Hawk's Underground 2 Skatopia level, as the locations of the collectible goals are the same. (Hyperlinked is a walkthrough of the original Skatopia by YouTuber BenedictPlays).

At any point during gameplay, remember to view your Goal List by pressing TAB on the Keyboard or Select/Back on a Controller. You can also view more details about the goals in the Pause Menu > View Goals and selecting a goal for details.

Get Headshots in order to fill your Special Meter. The amount of Headshots it takes to fill scales based on how many players are in your lobby. Once the meter is filled, Focus Mode automatically activates and grants you both Unlimited Ammo/No Reload & Slowed Zombie Movement for 30 seconds.

The Smoke Bomb Crate on the Brown Bowl by the Barn has been retrofitted to sell Octobombs! Simply purchase them for 2000 whenever convenient. Refills cost 1500.

The Toolbox is located next to Ryan Sheckler, and will allow you to Repair Ladders and Ziplines to achieve other goals. Required for Repairables.

Main Zipline
This is the Main Zipline that goes up the Giant Slope from the side of the House to the Top of the Mountain. Only repairable at the Top of the Mountain after clearing the Giant Slope Debris for 4000.

Side Zipline
This is the Zipline located on the side of the Mountain on the path near one of the Blue Ladders. Only repairable after getting to the top of the Mountain with the Green Shack Key, you must walk up the wooden ramp on the right side and repair it from above.

Barn Ladder
This is right next to the Power Switch and will Clear Debris to the left of the Brown Bowl. This also gives you roof access to the Barn.

Big Billboard Ladder
This is located on the path on the side of the Mountain on the way to the Arcade Machine past the Blue Ladders.

Blue Ladders
The Toolbox is NOT required to simply Kick Down the 2 Blue Ladders on the path that goes along the side of the Mountain. They must be Kicked Down from above to allow easy access to the Mountain Side Path from the House area.

The chainsaw is located at the top of a climbable tree at the top of the mountain after you unlock the top bowl with the Green Shack Key. You must have at least acquired the Green Shack Key to grab the Chainsaw. Once you get to the top bowl, you must clear the debris leading to the purple bus. Then, immediately to your left, clear the debris at the top of the Giant Slope. Once the Giant Slope is accessible, you can then reach the top of the level to climb the Tree and grab the Chainsaw.

Further down the hill towards the barn you will encounter the Burning Garbage Pile. Run into the Garbage Pile and you will be launched up towards the barn, and subsequently reach the Firework nested there. Run into the Firework while on fire to launch it. (Be quick, you'll only be on fire for a few seconds!)

Tag the Big Billboard
The Big Billboard is located at the top of a Repairable Ladder on the side of the Mountain above the Blue Ladders on the way to the Arcade Machine. Repair the ladder, climb up, and Press USE (F on Keyboard/X on Xbox Controller) on the Blank Canvas on the side of the Mountain to spray on the mural.

The AFK Room Teleport is located inside the Purple Bus at the top of the Mountain. Once inside, speak to the COD Soldier sitting at the fire to get Hints about what to do next as well as his M1 Garand & the Mule Kick Perk. After he mentions the Gas-powered Generator, the Gas Can will be available to be picked up at the start of the level next to the Quick Revive Perk Machine.

The Gas Can is part of the Main Easter Egg Quest in order to get the Arcade Machine Powered On as well as Ending the Game by escaping in Beaverhausen's RV.

The Empty Gas Can does not become available until you speak to the COD Soldier, find the Generator on your own, OR Complete All Story Mode Goals. The Can will remain empty until you Complete All Story Mode Goals, and access the hidden Training Area behind the Garage Doors in the AFK Room. The Garage Doors will open upon Completion of Story Mode. Once in the hidden Training Area, there is a Taxi Cab in the corner from which you can Siphon Gas. Place the Can near the Gas Tank of the Taxi Cab and Hold USE (F on Keyboard/X on Xbox Controller) for 30 seconds in order to Siphon the Gas. Once the Can is Filled, you can pick it up and take it to the Generator.

The Generator is also part of the Main Easter Egg Quest and is located next to the Arcade Machine/Mineshaft on the side of the Mountain. Once you have the Filled Gas Can, you must Fill up the Generator by Holding USE (F on Keyboard/X on Xbox Controller) for 10 seconds. Once the Generator is Filled, you now have access to the Powered-On Arcade Machine & Classic Mode.

Classic Mode is only available after Completing All Story Mode Goals and Filling the Generator with Gas from the Filled Gas Can. Classic Mode costs 5000 points every attempt and each attempt will last 2 minutes. Goal Completion status is saved across attempts; however, collectible goals WILL reset until completed. (for example, if you get 2 Bags of Dog Food, but Classic Mode ends before you get all 5, you will still have to get all 5 on your next attempt). Stat Points do NOT respawn and can only be acquired once. Stat Points are the only collectibles that are saved between Classic Mode attempts.

Goals:
High Score, Pro Score, & Sick Score
All Score Goals scale based on how many players are in your lobby. Simply achieve that score during 1 run of Classic Mode by killing zombies/dogs. This score will reset on every attempt.

Once Classic Mode is completed, the map will go to Night, and you will unlock the Day/Night toggle on the Arcade Machine located inside of the hidden Training Area next to the Classic Mode Perk Machines. These are accessible by double-jumping to the ledge, as you cannot lose your double-jump ability upon dying/getting downed. These Perk Machines & Bowie Knife are located here as a backup in-case you die or get downed and lose them. You can also freely toggle night and day modes by Holding USE (F on Keyboard/X on Xbox Controller) on the Arcade Machine on this ledge.

Once Classic Mode is Completed, you can then use the remaining Half Gas Can on the RV's Gas Tank to Fill it. Simply Hold USE (F on Keyboard/X on Xbox Controller) for 10 seconds to completely Fill the Tank. Once the RV is Filled, you can then End the Game on the RV Door for 30,000 Points.
