is there anythink i need to do in steam for the development console to work
Was the key for the dev console changed? If not what is it then? It used to be the ~ key so, I can confirm the Dev Console isn't working, unless the activate key was changed from activation key for the console to something else, Otherwise everything else is working fine.
This doesn't warrant a trainer update report just yet until we can confirm what key is needed to open the console once it's activated in the trainer but so far i've tried every key it seems and no response
