Resident Evil 3: Mercenaries Message Board  

I tried using this trainer for the Steam port of GOG's
original for The Mercenaries mode, but sadly, it didn't work.

I've just recently requested for a Steam version
of RE3's Mercenaries mode trainer...whether it gets
approved or not is a different story altogether.

I hope it does, I'm in dire need to have the same
cheats as the story mode but also include infinite time
since it's a timed game mode. especially if I wanna unlock
the AR, Minigun & Rocket Launcher for the main game.

Guess all I can do is wait, hope...and pray.

Indeed The Mercenaries mode is different game altogether with different exe, the trainer won't even recognize the process.
Good luck with that request.
