The song that plays while you're running is not a communist song. It's an anarchist anthem from the Spanish Civil War, "A Las Barricadas". You can clearly hear the spanish lyrics. I think the music is an adaptation of "Varshavianka", a russian, but pre-soviet, song. Bummer. And the game itself... I expected a different thing.
Love this game. Just like I love Crush The Castle and Siege Master... It's a genre, and they all are different games (maybe not so different, OK) And the music definitively rocks. How convenient.
it has its flaws. I had to finish it on low quality. i couldn't switch weaposn. BTW, I had to "guess" how to switch weapons in the first place, since it's not in the game instructions.
