Quick Scoop

“Co-stars” in Slap Battles usually refers to the Co-Op glove or getting the related badge/unlock path, and the exact steps depend on the current game version. I couldn’t verify the live in-game requirements right now, so the safest answer is to use the community guide route and check the glove’s badge condition in-game or on the Slap Battles wiki.

What to try

  • Open the game’s glove menu and look for the glove or badge tied to “Co-stars” / “Co-Op.”
  • Check whether it needs:
    • a specific badge,
    • a minimum slap count,
    • or a special challenge/map requirement.
  • If it’s a teamwork unlock, queue with a friend and coordinate the badge or objective together.
  • If the requirement is unclear, the Slap Battles community pages and discussions are usually the fastest place to confirm the current method.

Community angle

Recent public discussion around Slap Battles is mostly centered on guides, glove unlocks, and community Q&A rather than a single official walkthrough, which is why player-made instructions tend to be the most useful. The game’s wiki also notes that gloves are tied to slaps and badges, so unlock methods can change as new content is added.

Best next step

Use the in-game badge description as the source of truth, then compare it with the most recent wiki or subreddit guide before grinding for it.

TL;DR

The likely answer is: find the glove/badge tied to Co-stars, then meet its listed unlock requirement in-game ; if the wording is different on your screen, send me the exact badge or glove name and I’ll help decode it.
