COP BASTARD Steam Deck Status

No Valve badge was verified on the store page

The Steam store page checked on 30 October 2026 lists Windows system requirements and normal Steam features, but it does not display a confirmed Steam Deck Verified or Playable result in the material captured for this research. Until Valve publishes a badge, this site describes compatibility as community-reported.

A search-indexed reply attributed to developer targim. says optimization work was done and that the full release plays very well on Steam Deck. That is encouraging first-party context, but it is still not a Valve laboratory rating.

Use a short compatibility test

• Install through Steam and allow the default Proton choice first.
• Complete the tutorial before changing several settings at once.
• Watch frame pacing during smoke, sparks, and close-range firefights.
• Check text and controller prompts at the Deck’s native display size.
• Change one graphics option at a time and record the result.

Treat Proton reports as dated observations

ProtonDB can be useful for launch options and current player reports, but its entries can describe different game builds, Proton versions, or power settings. Match the report date and version before copying a fix. A launch-day report is not a permanent compatibility guarantee.

If the game starts normally, avoid adding launch flags simply because another player used them. Default settings give you a cleaner baseline and make regressions easier to reproduce.

What this page does not claim

This page does not award an unofficial Verified badge, promise a fixed frame rate, or claim battery life from a machine we did not test. A future Valve rating should replace this cautious status, not be mixed with it.
