Quantum Paradox is a single-player storyline modification for Half life 2 episode 2 in which you play as a person who does not remember his past and appears literally from nowhere. He has to overcome the dangerous trials of post-apocalyptic Petersburg, which has long been destroyed after a seven-hour war. Of the allies, he has a certain number of survivors, and of the enemies - a bunch of zombies and soldiers of the alliance!
I've been following Quantum Paradox since Lambda featured it, this look so amazing and I love that dark post-EP1 setting really looking forward ^^
