I linked to the Legacy mod on the previous page but having checked it again then wow what sort of messed up file host is that?
(Timer and probably full of fake "download" links leading to some horrible crap as if regular pop-ups weren't already shitty enough these days.)

That's the unlocker, dinput8.dll and the .cfg file go into the game folder, log is generated on the first run so didn't really have to be included but it doesn't really take any space so I bundled it in, readme file explains a bit on how it works.

And since the utility only works on the unpatched version of the game which by default requires Steam and a legit license for the game then as to not have to mess with the Steam debug console (steam://open/console as a URL command call to the Steam client.) and forcing a download of a older version of the game that way well the above is the old 1.0 exe and as another convenience as to not have to force a full re-check on a 50+ GB game which takes forever the 1.1 exe is included too.
The forums where this was originally posted (Cs.rin.ru) is still down after a attack and I don't know if they'll go online later this week or if it'll take longer so I couldn't check if there was a version compatible with the patched version of the game.
Patched version meaning the update released a few days ago, unpatched meaning the 1.0 release version on Steam and not the early leak from the disc version which appeared on the net about one day ahead of the games actual release date.
In-game just bring down the debug console as usual with Tilde / ~ and if listcvars returns ~3000 some commands instead of the few allowed ones in the unmodified version everything is working.
EDIT: Utility seems to be based on a similar program for DOOM(4) which I assume is from the same original author and yeah most cvars are identical but this game has a few new ones and they also removed a few existing commands. For me well aside from cheat commands I mostly enjoy testing things a bit and perhaps taking screenshots but the command to hide the hands is actually not available so that complicates things a bit.
