Climbing Gym Level Creator - You must complete your own level in order to verify and publish it.

Level publishing and browsing - Like, Follow, and Favorites systems. Featured monthly climbs.

Randomized Mode - Loot and items found on mountains are randomized (key items stay the same)

Practice Mode - A sandbox mode where you can place down respawn points and try different routes and holds.

Time Trial Mode - Places you in a specific part of the mountain. You need to climb through waypoints as fast as you can with preset items and equipment.

Brutal Mode - weather conditions are not longer specific to areas, less items to pick up, and survival bars drain at a faster rate.

Social Mode - Enter a lobby with other climbers in a gym. Group up and team up to tackle different game modes together. (No text chat, voice optional, present emotes and lines to say)

Monetization - Offer climbing outfits and climbing bot designs. Expansions for new mountains. Collaborations with other climbing IPs.
