trog69: Thanks for any help for this old, spazzy cheater. hehe
This cheat will not be the only one, what, old cheater?
A common problem: Players unable to play the game as it was meant to be are unable to cheat too. But there's a solution: Don't use a sack of mods, cheats, console commands ... but a single one!
For timid and/or talentless players gripped with fear of failure asking for cheats before the first start of the game I recommend the mod "Glorious Victorious +". After installation start the game and wait a few seconds, then press „1“ „2“ „+“ (without quotation marks!!!). No fear: You have 38 seconds to do so.*
This will lead you to the end of the game. You get any achievement available**, any gear etc. In a cutscene Geralt meets all friends and foes, and even some devs will appear – in disguise. They all praise Geralt and the artful playing of his master at the keyboard/controller. Then a bell rings.
Now you should shut down the computer (!!!) because in the next moment the cast – without exception and as if by command – begins to chuckle.
* As far as I know there's a cheat which extends this period - 5 minutes, as far as I heard.
** This mod adds achievements! Popular: Striding Goddess for moving one step forward without losing balance.
This should help. Now restart the game and you can begin a New Game +. Any stats of your equipment are set to "infinite". Somewhat disturbing: There's a permanent background chuckle swelling after each kill. But there should be a mod at nexus ...
Good luck! Hope I could help.
