Junkster is a 3D action platformer with a building mechanic. You play UM-13, use a robo-wrench, transform junk into functional routes, clear comic-book issues, collect COGs and stickers, and repair the crashed ship.
Junkster gameplay signals
Primary loop
Enter an issue, build useful paths from junk, fight or avoid mutants and bots, collect COGs, find secrets, and reach the exit portal.
Progression
The game is structured as comic-book issues, with later levels adding robot types, hazards, building puzzles, collectibles, and bosses.
Exploration
Each issue has routes, elevated platforms, hidden ledges, puzzle branches, and collectible detours that support replay and cleanup.
Multiplayer
Official store pages list Junkster as a single-player game; this wiki treats multiplayer as unconfirmed unless Stormcloud says otherwise.
Challenge
The main challenge is light platforming, building puzzle solving, collectible routing, and achievement cleanup rather than hardcore combat.
Verification boundary
Issue names, sticker count, achievement counts, and source-backed systems can be covered now; exact screenshots, timestamps, and full COG maps should be checked against gameplay footage and in-game capture.
Junkster gameplay guide boundary
The gameplay pages cover official mechanics, issue structure, current route notes, and achievement cleanup. Exact COG maps, screenshot routes, and deep boss strategies should be updated after direct in-game capture.
