TL;DR
- A console command (cl_physics_highlight_active 5) accidentally provides wallhack functionality to all CS2 beta players
- Popular streamers like fl0m and Ohnepixel verified the command works across different systems
- The glitch creates temporary legal cheating until Valve patches it out of the beta
- This highlights ongoing anti-cheat challenges despite the Source 2 engine upgrade
- Players should expect this temporary advantage to disappear in upcoming updates
Counter-Strike 2’s ongoing beta testing phase has revealed an unexpected development that’s temporarily reshaping competitive dynamics. While beta releases typically contain various bugs and glitches, few have the game-altering impact of this particular console command oversight.
The persistent cheating challenges that plagued previous Counter-Strike iterations were expected to diminish with the Source 2 transition. However, Valve’s current anti-cheat approach appears to have overlooked a critical developer command that’s now accessible to all players.
What makes this situation particularly noteworthy is that Valve intentionally left this command enabled, creating what players are calling ‘legal cheating’ during the beta period. This represents a significant departure from typical cheating scenarios where players actively circumvent game protections.

The discovery process unfolded during a live broadcast when content creator Erik “fl0m” Flom received viewer requests to test a specific console command. The initial expectation was that cl_physics_highlight_active 5 would simply highlight player models for visual clarity during gameplay.
Instead, the command produced dramatically different results than intended. Upon activation, distinctive green bounding boxes began appearing throughout Dust2, clearly marking player positions even when they were completely obscured by walls and other environmental objects.
Fl0m’s immediate reaction captured the community’s surprise, as he openly questioned whether he was now technically cheating. The discovery was quickly validated by other prominent streamers including Ohnepixel, who replicated the identical visual effects on their own systems.

The cl_physics_highlight_active command appears to have been designed as a developer tool for testing player model visibility and collision detection. However, the implementation oversight allows these visual indicators to render through solid objects that should normally block line of sight.
From a technical perspective, the command bypasses standard occlusion culling processes that typically prevent players from seeing through walls. This creates functionality nearly identical to traditional third-party wallhack cheats that cost significant money in CS:GO.
For competitive players, this creates an unusual scenario where advanced positioning knowledge becomes freely available. However, the temporary nature of this advantage means players shouldn’t become dependent on this crutch for their gameplay strategy.

The current situation exists in a unique ethical gray zone within competitive gaming. Since the command is natively available within the game client and doesn’t require external modifications, it technically doesn’t violate standard cheating policies during the beta period.
This raises important questions about intent versus implementation in game development. While Valve clearly didn’t intend for this to become a public wallhack tool, their decision to leave it enabled creates temporary permission for its use.
Competitively, this levels the playing field in an unexpected way—every player has equal access to this advantage, unlike traditional cheating where only some players gain unfair benefits.
Valve’s awareness of this command suggests its days are numbered. The development team likely already has patches in progress that will disable or modify this functionality before the full public release.
This incident provides valuable insights into the anti-cheat approach for Counter-Strike 2. It demonstrates that despite the engine upgrade, fundamental cheating vulnerabilities can still emerge from unexpected sources.
For the current beta period, players can technically use this command without fear of repercussions. However, this window will likely close abruptly with the next significant update, returning the game to its intended competitive balance.
The temporary nature of this phenomenon means players should enjoy it while it lasts but prepare for its inevitable removal. This serves as a reminder that beta features often contain temporary elements that don’t carry forward to final release versions.
Action Checklist
- Access CS2 console and enter cl_physics_highlight_active 5
- Test command functionality on Dust2 and other maps
- Document visual effects and range limitations for personal reference
- Monitor official patch notes for command removal announcements
- Prepare alternative strategies for when the command gets patched
