I came across this site alleging outcast cheat codes. Since I have not played the game I'm not sure if these work in Second Contact. If they are using the same game engine, which it appears they are, the codes should work (because they are integrated for/by developers) if they haven't shut them down before release.http://www.outcast-universe.com/media/cheats/
Also, just a quick word on the site Marian listed. There are a number of 'boomers who use their trainers for several of the Lara Croft games and haven't heard anyone ever having issues with them.
They even have their own Steam Community page, if that gives you any additional confidence: https://steamcommunity.com/groups/Cheathappens
"A world is supported by four things: The learning of the wise, the justice of the great, the prayers of the righteous, the valor of the brave, but all of these are as nothing without a ruler who knows the art of ruling - Make that the science of your tradition."
