I'm posting this as a warning to the community after attempting to contact the developer, Mike, via email and Reddit without a response.

A friend and I have discovered two significant issues with the multiplayer mode that I believe need to be brought to light.

Issue 1: Shuffled Order Visible to All Players

Unmodded console output revealing sequence

Without modifying the game, players can see the shuffled order of the shells, even when they're not the host, by simply opening the game via console.

Issue 2: Packet Manipulation

Code to make the current player to shoot themselves

With minimal coding knowledge, it's possible to send fake packets and make any player shoot any other player, including themselves. However, I want to emphasize that this problem may extend far beyond just manipulating shooting (which it's already overpowered), I just haven't tested yet.

Please be cautious: only play Buckshot Roulette Multiplayer with people you trust, as the current state of the game's multiplayer mode makes it difficult to ensure a fair experience.

I'll update this post if I receive a response from Mike or if any patches are released to address these issues.

If you have any questions or concerns, feel free to ask in the comments.

Update 1 (Nov 16): Well, a new version got released and after inspecting the code, it seems that nothing got fixed related to the problems talked about in this post. I also contacted moderators from Critical Reflex Discord server, still waiting for feedback.

Update 2 (Nov 17): Managed to talk to someone from the management of Critical Reflex, and issues are being sent to Mike.

Update 3 (Dec 13): Well, the new 2.2.0 update fixed most exploits, specially sending the sequence to the client, altho I'm yet to fully test the other exploits (5 in total before the update).

Update 4 (Dec 14): Alright, so out of the 5 fundemental exploits, only 2 got fixed (See shell sequence got reworked so it doesn't even send it, altho you can still see what is the next shell by using any items, and kick everyone midgame back to the lobby because Mike made it impossible to access it). The other 3 exploits are a bit limited in the new update but they still work. Trying to get in contact Mike, but we are close to Xmas so it might take a while.
