I am a christian from Hungary.
Dead Cyborg is not exactly a christian game, but it is about the meaning of the life, about the big questions: what is your worldview?
You can play the game for free, so it is a free/donation based game, check the homepage for downloads, more infos and donations: http://deadcyborg.com/
Sorry for my bad english. (In the game the english text is perfect of course.)
