Is there a cheat (through console or something) to add some nano catalysts?
I'd like to have back the 7k the game stole me because Crytek couldn't be bothered to test the product first -_-

?

Google for "Artmoney"

I just tried but after I search for the exact value there are thousands results and I can't filter because I can't spend points since the game was so kind to steal away even the few it didn't before -_-

do you know what is the exact parameter to modify?

?

You're modifying memory directly, so every time it will be different.

Search for the amount that you have (preferably not 0, as you can expect to find a lot of memory locations with 0)
Then find some in the game so the value changes.
Search within the results for the modified value.
