Here is the honest answer: Technically, no.

Resident Evil 6 uses Steam’s P2P multiplayer for co-op campaign and "Agent Hunt" (invading other players' games). The Resident.Evil.6.v1.0.Plus.9.Trainer-FLiNG Update Fix has no known VAC (Valve Anti-Cheat) bans associated with it because RE6 is not VAC-secured.

However, Capcom uses a rudimentary "Cheater Detection" flag. If you use Infinite Health or One-Hit Kills in a public co-op game, your partner will see what you are doing. They can report you, leading to a temporary "Quarantine" matchmaking ban (usually 24 hours).

Safe usage rule: Use the trainer strictly for Mercenaries No Mercy solo or Private Campaign lobbies. Do not use F6 (One-Hit Kills) in a public lobby. Infinite Stamina is usually invisible to other players.

As a "Plus 9" trainer, this tool offers a curated selection of cheats that cover the essentials without overwhelming the user with unnecessary toggles. The features typically include:

The "Update Fix" aspect of this release is crucial. Early versions of RE6 trainers often crashed the game during specific cutscenes or when loading between Leon, Chris, and Jake’s campaigns. This patched version demonstrates FLiNG’s attention to detail, resolving memory injection errors that plagued earlier builds.

Why it’s the best feature:

The standard. Your character (Leon, Chris, Jake, or Ada) will never enter the "dying" state. Even on "No Hope" difficulty, you can stand in front of a Napad or Ustanak without fear. Note: This does not prevent instant-kill QTEs (Quick Time Events) or falling off cliffs.
