Conclusion:

I would like to thank you in stead of everyone over here who has been waiting for a truly interesting and qualified campaign to have it's complete release as of now. This is one heck of a campaign, which I think everyone loves who has tried. The environment, the gameplay, all the authentic elements and the added zombie situation; these all are in perfect harmony with a difficult, yet enjoyable gameplay. Thank you again for all the hard work! It's PERFECT!
